In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 40 tests are conducted using a significance level of 10% approximately how many of the tests will incorrectly find significance?
Solution:
We are given
n = 40 tests
Significance level = 10% = 0.10
10% of n = 0.10*40 = 4
So, about 4 out of 40 tests will incorrectly find significance.

In this exercise, we are conducting many hypothesis tests to test a claim. Assume that the null hypothesis is true. If 400 tests are conducted using a significance level of 2 % , approximately how many of the tests will incorrectly find significance?
we are conducting many hypothesis tests to test a claim. Approximately how many of the tests will yield significant results by chance, if the null hypothesis is true? a. 600 tests using a significance level of 5%. b. 70 tests using a significance level of 10%.
Multiple Choice. Circle the best answer. Make sure your answer is clearly marked. Ambiguous responses will be marked wrong. In a hypothesis test for H0: m1 = m2 vs Ha: m1 > m2,we have a sample with x1=26, x2=23. The randomization distribution will be centered around 3. (a) True (b) False A statistical test is used to determine whether results from a population are convincing enough to allow us to conclude something about the sample. (a) True (b) False Which...
Question 10 In conducting a hypothesis test with we find a test statistic with a p-value of 0.0389. Let the significance level be .010. The researcher would have: found another significance level rejected the null hypothesis not been able to draw a conclusion about the null hypothesis not rejected the null hypothesis
