Does advertising influence children as young as three? Researchers at Stanford University conducted a taste test with preschoolers. Each preschooler tasted two identical samples of five food items (hamburger, french fries, chicken nuggets, baby carrots, and apple slices). For each item, the children tasted one sample wrapped in a McDonald's wrapper and the other sample in an identical, but unbranded, wrapper. Some children tasted the sample in the branded wrapper first, others tasted the sample in the unbranded wrapper first. Consistently for all food items, the majority of preschoolers preferred the food in the McDonald's wrapper over the one in the unbranded wrapper, even though both samples were identical. [Source: Robinson, T. N., et al. "Effects of fast food branding on young children's taste preferences." Archives of Pediatrics & Adolescent Medicine 161 C2007): 792–797]. The researchers found that the preschoolers who watched more television or ate more often at McDonald's were…

8. A local 7-Eleven sells a “Memory Pill" that is supposed to help people...um...remember. You find some Oxnard College students and randomly divide them into two groups of 15 students each. One group takes the actual "Memory Pill" and the other group takes the placebo. You then show them a list of 20 items and want them to remember as many as possible. The experimental group (those taking the pill) remembered an average of 12.3 items from the list, with a sample standard deviation of 5.4. The control group (with the placebo) remembered an average of 10.9 items, with a sample standard deviation of 4.2. Is this enough evidence to show that the "Memory Pill" improves...well...memory?

Skittles Original Fruit bite-size candies are multicolored candies in a bag, and you can "Taste the Rainbow" with their five colors and flavors: green, lime; purple, grape; yellow, lemon; orange, orange; and red, strawberry. Unlike some of the other multicolored candies available, Skittles claims that their five colors are equally likely. In an attempt to reject this claim, a 4-oz bag of Skittles was purchased and the colors counted. Does this sample contradict Skittle's claim at the .05 level?

A student who is a Senior, has the following grading scheme and grades in a hypothetical Quantitative Reasoning course: Homework, Quizzes, Class Participation and Attendance are worth 25%  Exam 1 is worth 20%  Exam 2 is worth 20%  Final exam is worth 35%  Just before the final, she has earned the following grades (all out of 100):  Homework grades: 100, 94.5, 0, 0, 0, 0, 0, 75, 100, 0, 84, 0  Exam 1: 100  Exam 2: 95  What is her homework average?  What percent of the entire semester's grading has been completed so far? What is her course grade average for that work?  What is the highest grade she can earn in the course if she is able to score 100 on the final?  But wait!  There is a 10 point BONUS on the exam.  Suppose she scores 110.  What is her grade then?  The University scoring scale is as follows:  A: 93 to 100;  A– : 90 to 93,  B+: 87 to 90  B: 83 to 87  B– : 80 to 83  C+ : 77 to 80,  C: 73 to 77  C – : 70 to 73  D+: 67 to 70  D: 63 to 67  D– : 60 to 63,  F: below 60.

Legal researchers were interested in learning whether a rape defendant's perceived guilt depends on the type of argument introduced by his defense attorney. Researchers classified each defense by whether or not it introduced the idea that the female victim was asking for the encounter—the “she shouldn't have worn that short skirt” defense. In a simulated juror situation, the researchers asked each of the 20 mock jurors to rate the guilt of the defendant on a scale from 1 to 7. This is a(n) _____ dependent variable, which means that the data can be analyzed using a _____ test. a. nominal; nonparametric b. ordinal; parametric c. ordinal; nonparametric d. nominal; parametric

mplete: Chapter 8 Problem Set ack to Assignment Attempts 6. A sports analogy for hypothesis tests V In recent years, professional sports have incorporated the use of instant replay in order to dispute questionable calls by the referees. For example, in the National Basketball Association (NBA) a head coach is allowed to challenge the referees' decision on whether a shot was made before time expired in the game. In order for the referees to reverse their original decision, the instant replay must exhibit clear evidence to the contrary, Suppose the referees rule that the last shot of the game was made before the clock had expired. The coach of the opposing team believes that time ran out before the shot was made, and the coach challenges the referees' decision. The referees will review all available evidence (video taken from different camera angles) and make a decision. If there is evidence beyond a reasonable doubt that their original call was incorrect, the basket won't count.…

6. An Instructor teaching three sections of Introductory Psychology, each section covering the same material. She has made up a different final exam for each section, but she suspects that one of the versions is more difficult than other two. She decides to conduct an experiment to evaluate the difficulty of the exams. During the review period, just before finals, she randomly selects five volunteers for each class. Class 1 volunteers are given version 1 of the exams, Class 2 volunteers get version 2, and Class 3 volunteers receive version 3. Of course, all volunteers are sworn not to reveal any of the exam questions and also, of course, all of the volunteers will receive different final exam from the one they took in the experiment. The following are the results. Does this study suffice the assumptions in employing One way anova in interpreting the results. Explain why or why not?
