State the null and alternative hypotheses we should use to test whether the population mean daily number of texts for 25- to 34-year-olds differs from the population daily mean number of texts for 18- to 24-year-olds. (Enter != for ≠ as needed.) H0: μ=128 Ha: μ!=128 (b) Suppose a sample of thirty 25- to 34-year-olds showed a sample mean of 118.1 texts per day. Assume a population standard deviation of 33.17 texts per day. Compute the p-value. (Round your answer to four decimal places.) p-value =
