A hypothesis test is performed with a significant level alpha = .05 then
a) If the P- value is .08 then H0 fails to reject because here P-value >0.05.
b) If the P- value is .08 then the results is not statistically significant at .05 level
c) If the P- value is .03 then H0 is rejected because here P-value <0.05..
d) Tf the P- value is .03 then the results is statistically significant at .05 level

When performing a hypothesis test, the p value is found to be 0.031. This means that: a) Ho is rejected at the level α = 0.05 but not at the level α = 0.01 b) Ho is rejected at the level α = 0.05, and at the level α = 0.01 c) Ho is not rejected at levels α = 0.05 and α = 0.01

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

Jane wants to run a hypothesis test with the significant level equal to 0.05. After collecting the data, she calculates that the p value is equal to 0.003. What are the appropriate next step? Please select the best answer. Conclude that the null hypothesis is rejected. Change the significant level to be 0.001, so that the null hypothesis is not rejected. Conclude that the null hypothesis is not rejected. Change the significance level to be 0.01, so that she can...
