Question 16 The p-value for a hypothesis test turns out to be 0.08969. At a 9% level of significance, what is the proper decision? Reject H0H0 Fail to reject H0
Which of the following statements about hypothesis is true? Question 16 options: When the null hypothesis is true, there is an evidence of difference between population means All of the statements are correct When the null hypothesis is false, the samples are considered the same. When the null hypothesis is true, there is no evidence of difference between population means.
Which of the following is correct about tests of hypotheses? Question 11 options: If we take a large enough random sample, any effect (however small) will be deemed statistically significant. The measure of statistical significance (a P- value) depends heavily on the sample size. Practical significance is not the same thing as statistical significance. If the consequences of rejecting the null hypothesis are very serious, we should conduct the test using a very small level of significance. All the statements above are true.
