- Which of the following p-values will lead us to reject the null hypothesis if the level of significance equals 0.025? a 0.015 b 0.150 c 0.250 d 0,051A book club wonders if fewer than 40 percent of students at a local university had read at least one book during the last year. To test the claim, the book club selected a random sample of students at the local university and recorded the number of students who had read at least one book during the last year. The club conducted a test with the hypotheses H0:p=0.40H0:p=0.40 versus Ha:p<0.40Ha:p<0.40. The test yielded a pp-value of 0.033. Assuming all conditions for inference were met, which of the following is an appropriate conclusion? At the significance level α=0.01α=0.01, the null hypothesis is rejected. There is convincing evidence to support the claim that fewer than 40% of the students at the local university read at least one book last year. A At the significance level α=0.01α=0.01, the null hypothesis is rejected. There is not convincing evidence to support the claim that fewer than 40% of the students at the local university read at least one book…Given null =34 and alternative doesnt equal 34. a P-value of 0.158 .
