Question:

The following output (from \(\mathrm{R}\) ) presents the results of a hypothesis test for a population mean \(\mu\).

image text in transcribed

a. Is this a one-tailed or a two-tailed test?

b. What is the null hypothesis?

c. What is the \(P\)-value?

d. Assume the population standard deviation is \(\sigma=1.6397\) and the sample size is \(n=100\). Use these values, along with other values in the output, to compute the \(P\)-value for the test of \(H_{0}: \mu \geq 69.3\) versus \(H_{1}: \mu
