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

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 $\sigma=11.6189$ and the sample size is $n=36$. Use these values, along with other values in the output, to compute the $P$-value for the test of $H_{0}: \mu=48$ versus $H_{1}: \mu eq 48$.
