Step 1 :In this example, \(\mu_{d}\) 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.
Step 2 :The null hypothesis (H0) is usually a statement of no effect or no difference. The alternative hypothesis (H1) is the statement that there is an effect or difference.
Step 3 :In this case, the null hypothesis would be that there is no difference in heights between mothers and their first daughters, which means the mean difference (\(\mu_{d}\)) is 0.
Step 4 :The alternative hypothesis would be that there is a difference in heights between mothers and their first daughters, which means the mean difference (\(\mu_{d}\)) is not 0.
Step 5 :\(\boxed{\text{The null hypothesis, } H0: \mu_{d} = 0 \text{ in.}}\)
Step 6 :\(\boxed{\text{The alternative hypothesis, } H1: \mu_{d} \neq 0 \text{ in.}}\)
