Assume that the null hypothesis is true. If 892 tests are conducted using a significance level of 2%, approximately how many of the tests will incorrectly find significance?
Homework Answers
If the null hypotheses are true and the tests use a significance level of 2%, the probability of a Type I error is 2%. Over 892 tests, this would give an average of 18 tests that (falsely) reject the null hypothesis.
The answer is 18.
Please give me a thumbs-up if this helps you out. Thank you!

Suppose a hypothesis test is conducted using a significance or alpha level of 0.05, and the null hypothesis is rejected. This means that? A we would also reject the null hypothesis if the significance level had been 0.10 instead of 0.05. B the p-value was greater than 0.05. C we would also reject the null hypothesis if the significance level had been 0.01 instead of 0.05. D All answer options are correct.

Assume a researcher published a paper rejecting a null hypothesis at the 1% level of significance (that is, α = 0.01), which of the following statements is true? The finding may not be significant since it was not tested at an alpha level of 0.05 You cannot make any assumptions about the alpha at the 5% level without first calculating the value from the published data It is 5 times as likely the null hypothesis would be accepted at the...

The null hypothesis must be rejected at a 5% level of significance. The null hypothesis must be rejected at a 1% level of significance. The null hypothesis must be rejected at both a 5% and a 1% level of significance. None of the above. same set For a hypothesis testing problem with a given data set, you have rejected the null hypothesis at a 10% level of significance. For the same data set,

If a null hypothesis is rejected at the 0.10 significance level but not at the 0.05 significance level, then the p-value of the test is between 0.05 and 0.10. True or false?

A consumer advocate conducted a hypothesis test at the 5% significance level to determine if the mean level of impurities in a bottled water product is higher than themanufacturer’s advertised value of 20 parts per million. The advocate collected 25samples, measured the impurities, calculated a test statistic and obtained a p-value of 0.0423. Which of the following correctly states the advocate’s conclusion and reason for the conclusion? A. Reject the null hypothesis because the p-value is smaller than the significance...

If a null hypothesis is rejected at a significance level of 1%, then we should say that it was rejected at 1%. Reporting that the null was also rejected at the 5% level of significance is unnecessary and unwise. True or false?
