1) For the following prompts, choose either INCREASE, DECREASE, OR UNCERTAIN to correctly complete the sentences. (3pts each) a. All else held constant, an increase in the sample size will the margin of error of a confidence interval of u when the population parameter o is unknown. b. When testing a hypothesis using the "critical z approach", an increase in the value of a will the critical z value, holding everything else constant. C. All else held constant, an increase in the confidence level will _the value of Za/2 when computing the margin of error of a confidence interval for u when the population parameter o is known d. All else held constant, an increase in the population size will_ _the width of the confidence interval when the population parameter o is known e. When testing hypothesis using the "p value approach", an increase in the confidence level will the value of a, holding everything else constant. f. When testing a hypothesis using a z test statistic, a decrease in the absolute value of the z test statistic will the p value, holding everything else constant. g. All else held constant, the standard deviation of the sampling distribution for, say, will if the sample size increases.
