Question

choice answers:
1) a decrease or increase
2)a decrease or increase in M, numerator or denominator of the test statistic for z, decrease or increase the overall stat, making it less or more likely you will reject the hypothesis
3) _ (same symbols as part 4) - increase or decrease in this denominator, increase or decrease the overall test statistic. this denominator decreases when the sample size (n) increases or decreases or the population standard deviation increases or decreases

Suppose you ae planning to use a best of the population mean when the population standard deviation is k test) to best the following one-tailed hypothesesmR Since you want to maximize the power of your study, you are considering which factors might increase pow you can adjust your plans to incorporate them, if possible, belfore oonducting your research considerations for i ncreasing power Fill in any missing words/values. (Hint Rememb The following are your for this albernative ive hypothesis, you will rejedt the nul hypothesis for large values of the test statistic) increases the power of the z test because this change in a makes it more likely you will reject the nul hypothesis This change makes it easierto oorredtly reject a false null hypothesis-meaning that poweris increased in M increases the power ofthe 2 test. because this change in tre of the test statistic for the z bestrt overall test statiste, Imaking it : -likely you will reject the null hypothesis. : test stetistic, making it more lkely you wil reject the hulhypotrhesis!

Explanation / Answer

1) Increases the significance level will increases the power of the z test.

2) Decrease in M Increases the numerator making it more likely to reject null hypothesis.

3)The denominator of the Z statistic is decreases. In this denominator increases the power of the Z test, because this change increases over all test statistic . Making it more likely you will reject the null hypothesis. The denominator decreases when either of the sample size increases or population standard deviation decreases.
