Question

women athletes at a certain university have a long-term graduation rate of 67%. over the past several years, a random sample of 38 women athletes at the school showed that 23 eventually graduated. Does that indicate that the population proportion of women athletes who graduate from the university is now less than 67%? Use a 5% level of significance.

State the null and alternate hypotheses.

What sampling distribution will you use?

What is the value of the sample test statistic? (Round to two decimal places.)

Find the P-value of the test statistic. (Round to four decimal places).

Based on your answers, will you reject or fail to reject the null hypothesis? are the data statistically significant at level a?

Interpret your conclusion in the context of the application. (sufficient or insufficient).

Answer #1

Women athletes at the a certain university have a long-term
graduation rate of 67%. Over the past several years, a random
sample of 40 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.
