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.

Please give correct Answers and Answer both parts. A B 6.13 Taste test. Some people report that just one sip, they can detect the difference between a diet and a regular Coke. A researcher wanted to test this claim, so he chose 80 persons at random. He then filled 80 simple white cups with soda, half diet and half regular, and asked each person to take one taste from their cup and identify the soda as diet or regular based on a random assignment. The drink was accurately identified by 53 of the participants. (a) Do these data show that these folks are any better or worse at telling the difference between diet and regular soda than random guessing? (b) Explain the significance of the p-value in this context.
The Student Union President conducted a survey to estimate the proportion of first year students who participated in the social activities organized by the Student Union. Which of the following surveying options does NOT affect the presidents ability to generalize the survey to all first year students. The president put the survey on the Student Union webpage a Monday and collected the responses at the end of the week. All of the other options present a problem for generalizing the results. The president polled all students coming out of the Student Union on a given Monday. The freshmen class consists of 3000 students. A random sample of only 300 were sent a survey. Only 150 responded. The survey was sent only to first year students enrolled in statistics courses because all students need to satisfy a statistics general education requirement.
