A random sample of 330 cases or observations reveals 190 successes. Test whether the population proportion of successes is different from 0.50 (let = 0.03). a) State the null and alternative hypotheses associated with the test. (0.5 point) b) What is the critical value of the associated test statistic? (0.25 point) c) What is the calculated value of the associated test statistic? (0.5 point) d) What is the p-value of the associated test statistic? (0.5 point) e) State your decision about the null hypothesis by comparing the critical and calculated values of the test statistic or by comparing p-value with (0.25 point)
