Ho =140; Ha: < 140 = 0.05 (significance level) = %0 = -0.52 p = 0.3015 Select the correct answer below: Reject the null hypothesis because the value of z is negative. Do not reject the null hypothesis because |-0.52] > 0.05. Reject the null hypothesis because the p-value 0.3015 is greater than the significance level a = Do not reject the null hypothesis because the p-value 0.3015 is greater than the significance level a Poiect the null hypothesis because 1-0 52 0.05 = 0.05. 0.05.
