Women athletes at a certain university have a long-term graduation rate of 67%. Over the past several years, a random sample of 36 women athletes at the school showed that 21 eventually graduated. Does this indicate that the population proportion of women athletes who graduate from the university is now less than 67%? Use a 10% level of significance. A USE SALT (a) what is the level of significance? (b) State the null and alternate hypotheses. O Ho: P< 0.67; H: p = 0.67 O Ho: p = 0.67; H,: p> 0.67 O Ho:P = 0.67; H;:p+0.67 OHo:p = 0.67; H,: p< 0.67 What sampling distribution will you use? O The standard normal, 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 Student's t, since np > 5 and ng > 5. What is the value of the sample test statistic? (Round your answer to two decimal places.)
