Textbook Question
Chapter 11, Problem 11P
College athletes, especially males, are often perceived as having very little interest in the academic side of their college experience. One common problem is class attendance. To address the problem of class attendance, a group of researchers developed and demonstrated a relatively simple but effective intervention (Bicard, Lott, Mills, Bicard, & Baylot-Cascy, 2012). The researchers asked each athlete in to text his academic counselor “in class” as soon as he arrived at the classroom. The researchers found significantly better attendance after the students began texting. In a similar study, a researcher monitored class attendance for a sample of n – 16 male athletes during the first three weeks of the semester and recorded the number of minutes that each student was lair to class. The athletes were then asked to begin texting their arrival at the classroom and the researcher continued to monitor attendance for another three weeks. For each athlete, the average lateness for the first three weeks and for the second three weeks were calculated, and the difference score was recorded. The data showed that lateness to class decreased by an average of MD – 21 minutes with SS = 2,940 when the students were texting.
a. Use a two-tailed test with α = .01 to determine whether texting produced a significant change in attendance.
b. Compute a 95% confidence interval to estimate the mean change in attendance for the population.

A clinical researcher would like to know whether a certain drug is more effective at treating
lepression than just psychotherapy alone. In order to study this topic, the researcher gains access to
a population of individuals diagnosed with depression and administers surveys to a random subset
of that population. To assess the relationship between therapy type and depression symptoms, the
survey asks participants what their current treatment plan involves (drug therapy, psychotherapy,
both drug and psychotherapy, or no therapy) and what their current depression symptoms include.
This study is a(n):

- Which type of fast-food chain fills orders most accurately at the drive-thru window? The Quick Service Restaurant (QSR) magazine drive-thru study visits restaurants in the largest fast-food chains in all 50 states. Visits occurred throughout the day, starting at 11:00 A.M and ending at 2:30 A.M. During each visit, the researcher ordered a main item, a side item, and a drink and made a minor special request such as a beverage with no ice. After receiving the order, all food and drink items were checked for complete accuracy. Any food or drink item received that was not exactly as ordered resulted in the order being classified as inaccurate. Also included in the measurement of accuracy were condiments asked for, napkins, straws, and correct change. Any errors in these resulted in the order being classified as innacurate. In 2015, the ethnic category including Del Taco, El Pollo Loco, Fazoli's, Panda Express, Taco Bell, and Taco John's had the fewest inaccuracies, with only 42 of 457…arrow_forwardIn a classic study, Shrauger (1972) examined the effect of an audience on performance for two groups of participants: high self-esteem and low self-esteem individuals. The participants in the study were given a problem-solving task with half of the individuals in each group working alone and a half working with an audience. Performance on the problem-solving task was measured for each individual. The results showed that the presence of an audience had little effect on high self-esteem participants but significantly lowered the performance for the low self-esteem participants. a. How many factors does this study have? What are they? b. Describe this study using the notation system that indicates factors and numbers of levels of each factor.arrow_forwardBelow is data from a study examining the effects of two different psychotherapy treatments on self-esteem. Specifically, two different treatment types (treat1 and treat2) were compared to a waiting list control group in terms of increasing self-esteem; the main question concerned whether each separate therapy type was different from no treatment at all. The values shown below are the self-esteem scores for the participants in each group (higher values indicate greater self-esteem). a. What inferential test did you use? b. Using an alpha level of .05, determine whether there were any mean differences between the groups of interest?arrow_forward
- Recent research indicates that the effectiveness of antidepressant medication is directly related to the severity of the depression (Khan, Brodhead, Kolts & Brown, 2005). Based on pretreatment depression scores, patients were divided into four groups based on their level of depression.

One of the early episodes originally depicted her suicide in graphic detail. Some critics and mental health advocates argued that the series represented suicide irresponsibly and worried that the show would lead to copycat suicides or self-harm. To test the effect of the show, Niederkrotenthaler et al. (2019) first used social media to determine the exact months of the year when the show was being discussed. They found that public attention was highest during April 2017. What type of design did they use?

In one part of the study, female college students were given brief descriptions of a potential romantic partner. The fictitious male was described positively as being single and ambitious and having good job prospects. For one group of participants, the description also said that he had a great sense of humor. For another group, it said that he has no sense of humor. After reading the description, each participant was asked to rate the attractiveness of the man on a seven-point scale from 1 (very unattractive) to 7 (very attractive). A score of 4 indicates a neutral rating. The females who read the “great sense of humor” description gave the potential partner an average attractiveness score of M = 4.53 with a standard deviation of s = 1.04.

Across all genders and age groups, people who do not drink tend to be healthier on average than people who do drink. However, people who drink regularly are on average healthier than those people who have recently stopped drinking.

However, they are still concerned about service. Recently, a group of four carriers hired Brunner Marketing Research Inc. to survey passengers regarding their level of satisfaction with a recent flight. The survey included questions on ticketing, boarding, in-flight service, baggage handling, pilot communication, and so forth. Twenty-five questions offered a range of possible answers: excellent, good, fair, or poor. A response of excellent was given a score of 4, good a 3, fair a 2, and poor a 1. These responses were then totaled, so the total score was an indication of the satisfaction with the flight. The greater the score, the higher the level of satisfaction with the service. The highest possible score was 100. Brunner randomly selected and surveyed…arrow_forwardDespite the availability of several modes of transportation, including metro and ride-booking services, most people in the Washington, D.C., area continue to drive their own cars to get around (The Washington Post, June 6, 2019). According to a survey, 62% of area adults use their own cars daily. Suppose only 38% of the area’s adults under 35 use their own cars daily. It is known that 43% of the area’s adults are under 35. What is the probability that a Washington, D.C., area adult is under 35 and uses his/her own car daily? If a Washington, D.C., area adult uses his/her own car daily, what is the probability that he/she is under 35?arrow_forward
