Question:

For a test of \(\mathrm{H}_{0}: p=0.50\), the sample proportion is 0.35 based on a sample size of 100 .

a. Show that the test statistic is \(z=-3.0\).

b. Find the \(\mathrm{P}\)-value for \(\mathrm{H}_{a}: p<0.50\) using, e.g, the Normal Distribution app.

c. Does the \(\mathrm{P}\)-value in part \(\mathrm{b}\) give much evidence against \(\mathrm{H}_{0}\) ? Explain.
