Hypatia is a financial analyst who is exploring the effects a new employer-supported childcare program has on the proportion of personal days her employees take off of work due to family issues. She predicts that the proportion is less than 15%. To test this prediction, she surveyed 500 random employees and found that 165 of them took off more than 15% personal days due to family issues. The following is the setup for this hypothesis test: H0:p=0.15 H0:p<0.15 The p-value for this hypothesis test is 0.05. At the 2.5% significance level, should she reject or fail to reject the null hypothesis?
