1.A researcher conducts a hypothesis test and fails to reject the null hypothesis at the 0.05 level of significance.Based only on this information, I may conclude that (Circle one):

(a)I would fail to reject the null hypothesis if the level of significance was 0.01 rather than 0.05.

(b)I would reject the null hypothesis if the level of significance was 0.01 rather than 0.05.

(c)I would accept the alternative hypothesis if the level of significance was 0.01 rather than 0.05.

(d)Cannot be determined from the given information.

2. Suppose a researcher wishes to determine the sample size necessary to estimate the population mean and achieve a specified margin of error with 90% confidence.Holding everything else constant, changing the confidence level to 99% would require (Circle one):

(a)A larger sample size

(b)A smaller sample size

(c)The same sample size

(d)Depends on the situation
