A recent issue of the AARP Bulletin reported that the average weekly pay for a woman with a high school degree is $520 (AARP Bulletin, January–February, 2010). Suppose you would like to determine if the average weekly pay for all working women is significantly greater than that for women with a high school degree. Data providing the weekly pay for a sample of 50 working women are available in the file named WeeklyPay. These data are consistent with the findings reported in the AARP article. Complete D
null hyposthesis: H(o)=520Alternative hypothesis: H(a): greater then 520
sample mean=637.94
the test statistic = 5.62
p-value=0.00
Using a=.05, we would reject the null hypothesis.
D. Repeat the hypothesis test using the critical value approach.
