Question

1. if a studys p - value is 0.03, and the significance level is set at 0.05, what should be concluded?

a. increase the sample size and retest.
b. reject the null hypothesis.
c. the result is likely due to chance.
d accept the null hypothesis.

Explanation:

In hypothesis testing, if the p - value ($0.03$) is less than the significance level ($0.05$), we reject the null hypothesis. A p - value less than the significance level indicates that the observed result is unlikely to have occurred by chance under the null hypothesis.

Answer:

B. Reject the null hypothesis.
