Of a random sample of 187 auditors, 73 indicated some measure of agreement with the statement "Cash flow is an important indication of profitability." Test at the 1% significance level against a
two-sided alternative hypothesis the null hypothesis that one-half of the members of this population would agree with this statement. Also find and interpret the p-value of this test.
