(a) For a given data, suppose a null hypothesis Ho is rejected at significance level a = 1%. True or False: With the same data, the null hypothesis Ho will also be rejected at significance a = = 5%. (b) Consider a one-tailed t-test for a null hypothesis Ho: 20. True or False: Larger values of the t-statistic provide more evidence for the null. (c) True or False: Assuming everything else remains the same, in order to reduce the width of a 95%-confidence interval by a factor of four, we need twice as many data points.

(a) For a given data, suppose a null hypothesis Ho is rejected at significance level a = 1%. True or False: With the same data, the null hypothesis Ho will also be rejected at significance a = 5%. (b) Consider a one-tailed t-test for a null hypothesis Ho: μ ≥ 0. True or False: Larger values of the t-statistic provide more evidence for the null. (c) True or False: Assuming everything else remains the same, in order to reduce the width of a 95%-confidence interval by a factor of four, we need twice as many data points.
