x = mm Then, compute the sample standard deviation, s. Report your answer with two decimals of precision. S = mm Next, compute the t-statistic of the test. Report your answer with three decimals of precision. t-statistic = Then, use software to calculate the P-value for the test. Report your answer with three decimals of precision. 22 MAL 1 18 NAQuestion 27 of 34 > Finally, state the decision and conclusion of Max's test. Max decision the ...... The conclusion is that the current mean wing size of adult male monarch butterflies Answer Bank is equal to 37.7 mm no conclusion can be made about there is sufficient evidence that cannot make a should make the to fail to reject alternative hypothesis because the requirements have not been met is greater than 37.7 mm null hypothesis is different than 37.7 mm is less than 37.7 mm to reject there is insufficient evidence that about MAR 1 18 stvQuestion 27 of 34 Suppose that Max is a climate change scientist and butterfly enthusiast. In Max's locale, the mean summer temperature over the last ten years was higher than it was in the previous ten years. Max wonders if the size of adult male monarch butterflies has changed with the temperature difference. He knows that in his locale, historically, the mean rear wing length of adult male monarchs was 37.7 mm. He collects a random sample of n adult male monarchs to compare to the historical average. His sample data is shown in the given stem-and-leaf plot, where the stem unit is mm and the leaf unit is tenths of a mm. 36 6 37 2 5 5 6 7 7 8 8 8 9 9 38 1 2 3 3 4 5 5 6 7 39 0 2 4 Leaf unit = 0.1 mm From experience, Max knows that the rear wing length of monarch butterflies is normally distributed. He decides to use a t- test with a significance level of a - 0.05 to test the null hypothesis, Ho : M = 37.7 against the alternative hypothesis, H1 : M # 37.7, where u is the population mean. If the requirements for a t-test have not been met, only state the test decision and conclusion. Otherwise, find the mean, standard deviation, t-statistic, P-value, and state the test decision and conclusion. First, compute the mean, x, of Max's sample.
