The results of the National Health and Nutrition Examination Survey for the year 2011-12 found that 12.9% of the adults of age 20 and more in the United States had high total cholesterol. Assume that a researcher surveys a sample size of 120 for above 20 years. Construct a 95% confidence interval estimate for the population proportion so that the cholesterol level is the same as 12.9% (PHStat).

The nutrition label on a bag of potato chips says that a one ounce (28 gram) serving of potato chips has 130 calories and contains ten grams of fat, with three grams of saturated fat. A random sample of 35 bags yielded a conﬁdence interval for the number of calories per bag of 128.2 to 139.8 calories. Is there evidence that the nutrition label does not provide an accurate measure of calories in the bags of potato chips? Group of answer choices A, None of the above answers is correct. Because 130 is inside the confidence interval, we have convincing evidence that the true average is any different than what the nutrition label suggests. Because 130 is inside the confidence interval, we know for certain that the true average is any different than what the nutrition label suggests. Because 130 is inside the confidence interval, we do not have convincing evidence that the true average is any different than what the nutrition label suggests.

A recent survey of cell phone users indicated that 56 percent of the respondents prefer to use cell phones for texting rather than for making phone calls. A 95 percent confidence interval for the estimate of all cell phone users who prefer to use cell phones for texting has a margin of error of 3 percent. Assume all conditions for inference have been met. Based on the confidence interval, which of the following claims is supported? Select A, B, C, or D Less than half of all people prefer texting. A More than half of all people prefer texting. B At least 60 percent of all people prefer texting. C At least 75 percent of all people prefer texting. D At least 95 percent of all people prefer texting. E

During a flu vaccine shortage in the United States, less than a majority ofpeople were able to receive the vaccine. The results of a survey given to a random sample of 2,350 vaccine-eligible people indicated that 978 of the 2,350 people had received flu vaccine. b.Suppose a similar survey will be given to vaccine-eligible people in Canada by Canadian health officials. A 95 percent confidence interval for the proportion of people who will have received fluvaccine is to be constructed. Using 0.5 as your estimated proportion, what is the smallest sample size that can be used to guarantee that the margin oferror will be less than or equal to 0.02?
