Question
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 0.01 significance level to test the claim that there is no difference in heights
between mothers and their first daughters.
Mother
61.0 69.0 60.0 66.0 65.5 64.0 63.5 63.0 68.5 69.0 D
Daughter
63.5 68.0 62.0 67.0 65.2 69.0 63.5 63.0 66.0 70.0
In this example, Ha 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
in.
H1: Hd
in.
(Type integers or decimals. Do not round.)
Identify the test statistic.
t= (Round to two decimal places as needed.)
Identify the P-value.
P-value =
(Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
Since the P-value is
V the significance level,
the null hypothesis. There
V sufficient evidence to warrant rejection of the claim that
there is no difference in heights between mothers and their first daughters.
