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. In this example, H 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? Ho: Hd = H₁: Hd # (Type integers or decimals. Do not round.)

Transcribed Image 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.
In this example, Hd 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?
