A 2019 Gallup Poll asked a national random sample of 515 adult men to state their current weight. The mean weight in the sample was ?¯=194.. We will treat these data as an SRS from a Normally distributed population with standard deviation ?=32.. Give a 99%confidence interval for the mean weight of adult men based on these data. Give your answer as an interval in the form (*, *). Give your numbers to two decimal places. 99% confidence interval: Is this interval you have computed trustworthy as a 99% confidence interval for the mean weight of all U.S. adult men? Why or why not? There is probably little reason to trust this interval; it is possible that many of the men either wouldn't know their current weight or would lie about it. This interval would probably be more trustworthy if the poll contacted men with a wider range of different weights. This interval can be trusted since a 99%confidence interval can be expected to be relatively accurate. This interval can be trusted and seen to be around 99% accurate.
