In this problem, youl get an advance look at these concepts. Recall that CalAmity's first survey question asked, 'On a scale of 1 to 5, with 1 being "not terrified at all, actualy kind of excited in a good way" and 5 being"so terified rm buying diapers," how terrified are you that Gourmando is coming to town? Suppose that when Mr. Amity asked this question, he found that the average rating was 4.1, with a standard deviation of 0.2. The 2-score that corresponds to a 95% confidence level is 1.96, and by multiplying the 2-score by the standard deviation, you can get the margin of error that corresponds to a 95% confidence level. Cal Any multiplies 0.2(1.96) 0.392, and he reports that he s 95% confident that the average rating is 4.lt 0.392 on a scale of 1 to 5 Select the answer that most accurately completes the foliowing sentence If Cal Amity applies this statistic to the enire popuilation to estimate the parameter then There is a 95% chance that everyone in the population wil.nswer 4.1. It is not possible for Cal Amry to predict wnat tne parameter would be. it is highly likely thet the parameter would be betiween 3.708 and 4.492 There is 5% chance that the parameter would be between 3.708 and 4.492, but not equal to Θ 4.1

Answer 1

3)

The 95% confidence interval defines a range of values that you can be 95% certain contains the population mean.
option C) is correct

It is high likely that the parameter would be between 3.708 and 4.492
