Your daughter is doing a case study with my husband to know which devices are used by the students in their online classes. As such, a survey was conducted to 100 engineering students at PUP. 54 of them use smartphone, 37 use laptop and 24 of the respondents use iPad. 21 of them use both smartphone and laptop. 13 of them use both iPad and smartphone. In addition to that, 18 of them use both iPad and laptop. Only 9 of the respondents use all the three devices in their online class. Those who do not have any devices are studying through modular approach. How many respondents are modular?

A marine research team records the number of fish from 3 species that they find at different depth categories in the ocean. They are interested in assessing whether or not there is a relationship between the depth category (close to surface, mid-level, ocean floor) and the fish species found (species A, species B, species C). A two-way table showing the classification of a sample of 150 observations is given below. Give the degrees of freedom that would be used in a test of whether or not there is a relationship between the depth category (close to surface, mid-level, ocean floor) and the fish species found (species A, species B, species C). Degrees of freedom = The test is carried out at significance level α = 0.05 using the method described in the lecture notes. The decision is to reject the null hypothesis. What is the appropriate conclusion for the test? Select the appropriate conclusion from the list below. There is sufficient evidence at α = 0.05 that the variables for…
You are a professor interested in studying the relationship between social media and mental health. You immerse yourself in the literature and read dozens of research articles. After reading the articles it was evident the field claims adolescents with more than 100 social media interactions (post, likes, comments, reactions) will have anxiety. You want to test this claim and decided to carry out a research study. Before you go out to recruit adolescents at a middle school you need to choose an instrument to use in your study that assess anxiety levels. You found two instruments after searching the internet. One instrument, called Form A, cost money to use it and is the gold standard in assessing anxiety levels in adolescent. The other instrument is a free instrument developed by a professor called Form B. You don't want to spend a lot of money buying Form A. If Form A positively correlated with Form B you can justify using Form B in your study. You get a random sample of 10…

UCLA conducted a survey of more than 263,000 college freshmen from 385 colleges in fall 2005. The results of students' expected majors by gender were reported in The Chronicle of Higher Education (2/2/2006). Suppose a survey of 5,000 graduating females and 5,000 graduating males was done as a follow-up last year to determine what their actual majors were. The results for males are shown in the table below. The second column in the table does not add to 100% because of rounding.Conduct a goodness-of-fit test to determine if the actual college majors of graduating males fit the distribution of their expected majors.

You have two groups of researchers getting data on a new drug for Alzheimer’s patients with working memory loss. Both researchers give the same memory task performed using the Wisconsin Card Sorting Task and count the number of correct answers from 15 patients each.The results of Researcher A are: 60, 62, 70, 55, 78, 53, 78, 53, 70, 66, 62, 79, 51, 65, 69The results of Researcher B are: 68, 75, 71, 65, 58, 74, 68, 72, 60, 59, 72, 65, 70, 72, 69Which set of scores has a lower SEM? You should be able to do this just by looking at the raw scores, but of course you can do the math if it helps you answer the question.
Resting heart rate varies among different people. Design an experiment and examine whether or not a particular variable (e.g. fitness level, smoking, activity, age, gender) has an effect on heart rate. Begin by making one or more observations. Then formulate a hypothesis that can be tested. Finally, design an experiment to test your hypothesis! You can use yourself and any person you can talk to including family and friends Observations: State one or more observations related to your scientific Observation(s): The Heart rate will change depending on activity Hypothesis: Generate a hypothesis and include a justification for your Hypothesis: Male that are active will have a higher hear rate than females Experiment: Describe your experiment below and state the independent and dependent variables you will be exploring. Explain any specific instructions, e.g. how it will be carried out, how any measurements are to be made, if needed, etc……
A serious side effect of allergy medicines is that they cause drowsiness, which can cause many problems for the individuals taking them. In recent years, a new non-drowsy allergy medicine has been developed. The company that created the medicine claims to be the first, once-a-day, non-drowsy allergy medicine (call it Medicine A). An independent research group wanted to check on this claim by comparing Medicine A with another allergy medicine not advertised as non-drowsy (call it Medicine B). A random sample of 3,193 allergy sufferers was selected and each individual was randomly assigned to take either Medicine A or Medicine B. From the Medicine A group, 114 of 1,604 reported drowsiness and from the Medicine B group, 155 of 1,589 reported drowsiness. a) Calculate and label the two sample proportions separately. Next, calculate the difference between these sample proportions by subtracting (Medicine A – Medicine B). Complete these calculations by hand, label each of them, and present…

According to Inc.com, 71% of job seekers used social media in their job search in 2018. Many believe this number is inflated by the proportion of 22- to 30-year-old job seekers who use social media in their job search. A survey of 22- to 30 -year-old job seekers showed that 310 of the 370 respondents use social media in their job search. In addition, 275 of the 370 respondents indicated they have electronically submitted a resume to an employer.
