The sign test is a very simple procedure for testing hypotheses about a population median assuming only that the underlying distribution is continuous. To illustrate, consider the following sample of 20 observations on component lifetime (hr):

test statistic is Y = the number of observations that exceed 25.

a. Determine the P-value of the test when Y = 15.

b. For the given data, should H0 be rejected at significance level .05?
