Use the data in Exercise 6.22 to calculate the two-sided P value for a test of the null hypothesis that the population mean is 37,408.

Exercise 6.22

Data were obtained for 16,405 women who immigrated to the United States and their adult daughters at matching times of their lives [5]. The median income in the mothers’
and daughters’ ZIP codes were used to measure economic status. Consider this database to be a population, from which a random sample of 25 mothers was selected with these ZIP-code incomes. Calculate a 95 percent confidence interval for the population mean. Does your confidence interval include the actual value of the population mean, μ = 37,408?
