A survey was conducted in which both men and women were asked a question about a current issue. Possible responses to this question were “in favor of,” “not in favor of,” or “no opinion.” A chi-square test is to be used to determine whether the response to this question is independent of gender. The number of degrees of freedom for the chi-square test in this situation is
The data is presented in parallel format. Before running the ANOVA in Excel, you will need to put it
into serial (column) format. You will need to create a categorical variable for the first factor (days)
and for the second factor (time of day). This is a critical step.
The data presented shows exam scores for students randomly assigned to the sections meeting on
these days at these times of the day:

Let's talk that scenario and work with some fictional data from it: Let's imagine there was a question on the survey that asks "On average, how many times a day do you worry about COVID-19, either for yourself, family, or community? Below is some data for 10 respondents.
In the text box below (NOT on your scratch work),describe all of the steps you would use to calculate the appropriate type of t-test (independent or paired samples), given we want to compare Trump voters to Clinton voters.
***For this question, just list the steps - do not do any calculations. Since you are only able to see one question at a time, it's recommended that you also jot these steps down somewhere you can use them for the next question
That will be in the next question.
Your list will have at least 6 steps. Your last steps will involve the hypothesis test.

Hot duplicates the extra warmth provided by the mother python, and cold duplicates the absence of the mother. The table shows the result of the experiment. The researchers will use a chi-square test for homogeneity to analyze the findings.

The new results are shown in the 2 x 2 data matrix below: Observed Frequencies Color Preference Red Yellow Female 212 120 Male 80 188 The x2 test statistic for the chi-square test of independence would now be 68.64, and the phi-coefficient would be Thus, when we change the sample size without changing the proportions, the does not change, but the does. Now, suppose you conduct a slightly different study. Instead of looking at the difference between the preferences of males and females for two colors, you classify your 250 respondents into four categories: male child, female child, male adult, and female adult. You also decide to look at differences in preferences for five (5) colors: red, yellow, green, blue, and purple.

The survey conducted included drivers aged 16 to 61 years selected from 48 lorry stations in Ghana. Assume that this result holds true for the 2019 population of all such drivers in Ghana. In a recent random sample of 1600 drivers aged 16 to 61 years selected from Ghana, 83% said that they have talked on their cell phones while driving. Find the p-value to test the hypothesis that the current percentage of such drivers who have talked on their cell phones while driving is different from 81%.

The drug is safe, with no side effects. An experiment is conducted in which 8 randomly selected subjects are given the drug and then given a short time to memorize a list of 10 words. The subjects are then tested for retention 15 minutes after the memorization period. The number of words correctly recalled by each subject is as follows: 8,9,10,6,8,7,9,7. Over the past few years, the psychologist has collected a lot of data using this task with similar subjects and has obtained a mean of 6 words correctly recalled (the data were normally distributed).
