Women athletes at the a certain university have a long-term graduation rate of 67%. Over the past several years, a random sample of 37 women athletes at the school showed that 23 eventually graduated. Does this indicate that the population proportion of women athletes who graduate from the university is now less than 67%? Use a 1% level of significance. (a) What is the level of significance? State the null and alternate hypotheses. О но р3 0.67;B H: р> 0.67 O Ho: p < 0.67; H, : p = 0.67 O Ho: p = 0.67; H: p + 0.67 О на: р3 0.67; H,: р< 0.67 (b) What sampling distribution will you use?

How would you figure this out?

Women athletes at the a certain university have a long-term graduation rate of 67%. Over the past several years, a random sample of 37
women athletes at the school showed that 23 eventually graduated. Does this indicate that the population proportion of women athletes who
graduate from the university is now less than 67%? Use a 1% level of significance.
(a) What is the level of significance?
State the null and alternate hypotheses.
О но р3 0.67;B H: р> 0.67
О но: р<о.67; H,: р 3 0.67
O Ho: p = 0.67; H: p + 0.67
О на: р3 0.67; H,: р< 0.67
(b) What sampling distribution will you use?
O The Student's t, since np > 5 and ng > 5.
O The standard normal, since np > 5 and ng > 5.
O The Student's t, since np < 5 and ng < 5.
O The standard normal, since np < 5 and ng < 5.
What is the value of the sample test statistic? (Round your answer to two decimal places.)
(c) Find the P-value of the test statistic. (Round your answer to four decimal places.)
