A random sample of n = 200 observations is selected from a binomial population. The sample estimate of the proportion of successes is 0.13. Using a significance level of α = 0.10, we want to test: Ho: p = 0.10 Ha: p > 0.10 Assuming that we can use large-sample procedures, calculate the value of the test statistic needed to test these hypotheses.
