In a two tailed test if the p value is less than the significance level alpha, then: (Ch 10)

A. H₀ is rejected

B. H₀ is not rejected

C. H₀ may or may not be rejected depending on the sample size n

D. Additional information is needed and no conclusion can be reached about whether H₀ should be rejected

Solution

If the p value is equal to or smaller than the significance level , it suggests that the data is inconsistent with the assumption that the null hypothesis is true, so the null hypothesis must be rejected

Hence option A is correct

Note: Its better to calculate the critical value as well as the value of the test static to arrive at the conclusion
