Question 9

Extracted text: Listed in the accompanying table are heights (in.) of mothers and their first daughters. The data pairs are from a journal kept by Francis Galton. Use the listed paired sample data, and assume that the samples are simple random samples and that the differences have a distribution that is approximately normal. Use a 0.05 significance level to test the claim that there is no difference in heights between mothers and their first daughters. Mother 65.5 63.0 63.0 67.0 66.0 66.5 62.0 64.0 64.0 63.0 O Daughter 65.563.0 65.0 67.0 67.0 69.2 68.0 69.0 65.5 66.0 In this example, He is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the daughter's height minus the mother's height. What are the null and alternative hypotheses for the hypothesis test? Họ: Ha in H H Uin. (Type integers or decimals. Do not round.
