A survey was conducted two years ago asking college students their top motivations for using a credit card. To determine whether this distribution has changed, you randomly select 425 college students and ask each one what the top motivation is for using a credit card. Can you conclude that there has been a change in the claimed or expected distribution? Use a= 0.05. Complete parts (a) through (d). New Survey Frequency, f 112 Response Old Survey % Rewards Low rates Cash back Discounts Other 28% 23% 97 22% 109 7% 48 20% 59 a. State Ho and H, and identify the claim.

A study was done to look at the relationship between number of lovers college students have had in their lifetimes and their GPAs. The results of the survey are shown below. Lovers 4 8 3 7 0 6 5 6 GPA 2.7 2.3 3.4 2.4 3.5 2.9 2.7 2.8 r2r2 = (Round to two decimal places) Interpret r2r2 : There is a large variation in students' GPAs, but if you only look at students who have had a fixed number of lovers, this variation on average is reduced by 80%. Given any group of students who have all had the same number of lovers, 80% of all of these studetns will have the predicted GPA. 80% of all students will have the average GPA. There is a 80% chance that the regression line will be a good predictor for GPA based on the number of lovers a student has had. The equation of the linear regression line is: ˆyy^ = + xx (Please show your answers to two decimal places) Use the model to predict the GPA of a college student who as had 7 lovers.GPA = (Please round your…
CURSED MOVIE Released in 1956, the movie The Conqueror attracted considerable attention because many members of the cast and crew died from cancer supposedly resulting from exposure to radioactive fallout. The movie was shot a short distance from a site in Nevada where above-ground tests of atomic weapons were conducted. Among the 220 cast and crew members, 91 developed cancer. According to the National Cancer Institute, for that time period and for the age cohort, the incidence of cancer was about 40%. Use a 0.05 significance level to test the claim that the sample of cast and crew members is from a population in which the rate of cancer is greater than 40%. What do you conclude about the movie being a curse? Find null hypothesis and alternative hypothesis. Find test statsistic. Find P-value. How do you find p hat

No written by hand solution The Coca-Cola Company reported that the mean per capita annual sales of its beverages in the United States were 459 eight-ounce servings (Coca-Cola Company website, February 25, 2017). Suppose you are curious whether the consumption of CocaCola beverages is higher in Atlanta, Georgia, the location of Coca-Cola’s corporate headquarters. A sample of 61 individuals from the Atlanta area showed a sample mean annual consumption of 479.5 eight-ounce servings with a standard deviation of s = 90 ounces. Using α = .01, does the sample support the conclusion that means annual consumption of Coca-Cola beverage products is higher in Atlanta? Use both the critical value and p-value approach to test the hypothesis that H0: µ >459 in Atlanta vs. the 1-sided alternative. 7. From data from the past 10 years, we know that South Mall Theater averaged 600 patrons per day, with variance equal to 1000. This year, based on data from 25 random days, we found that the…
