The p-value is NOT equal to α, the level of significance of the hypothesis test.
True or false?
Homework Answers
False pvalue can be between 0 ana 1 and sometimes is also equal to level of significance such as 0.01 ,0.05 and 0.10. Higher p value means weak evidence against null hypothesis and when p value is less than 0.5 than we have strong evidence against null hypothesis. Moreover when p value is equal to level of significance than we reject the null hypothesis.

A hypothesis test is performed at the α = 0.05 level of significance. The p-value is determined to be 0.03. Therefore, we know that we would _______________. either reject or fail to reject the null hypothesis, depending on the value of the test statistic. reject the null hypothesis know that a 99% confidence interval would contain the value specified in the null hypothesis. fail to reject the null hypothesis

Briefly discuss the difference between the "Alpha level" (α) and the "p-value". True or False: Reject the null hypothesis when α = 0.042 and p-value = 0.03 True or False: Retain the null hypothesis when α = 0.02 and p-value = 0.010 True or False: Reject the null hypothesis when α = 0.01 and p-value = 0.005 True or False: Retain the null hypothesis when α = 0.001 and p-value = 0.02

The P-value for a hypothesis test is 0.079. For each of the following significance levels, decide whether the null hypothesis should be rejected. a. alphaequals0.05 b. alphaequals0.10 a. Determine whether the null hypothesis should be rejected for alphaequals0.05. A. Reject the null hypothesis because the P-value is equal to or less than the significance level. B. Do not reject the null hypothesis because the P-value is equal to or less than the significance level. C. Reject the null hypothesis because...
Which of the following is NOT true about the level of significance of a hypothesis test?...
Which of the following is NOT true about the level of significance of a hypothesis test? The larger the significance, the higher the risk that we make an error The level of significance is the maximum risk we are willing to accept in making an error. The significance level is also called the α level The significance level is determined by your sample size
