**Transcription for Educational Website****Statistical Analysis of Graduation Rates for Women Athletes**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 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 1% level of significance.**(a)** What is the level of significance?- 0.01 or 1%**(b)** State the null and alternate hypotheses.- \( H_0: p = 0.67; H_1: p < 0.67 \)- \( H_0: p > 0.67; H_1: p = 0.67 \)- \( H_0: p = 0.67; H_1: p \ne 0.67 \)- \( H_0: p < 0.67; H_1: p = 0.67 \)**What sampling distribution will you use?**- The standard normal, since np ≤ 5 and nq ≤ 5.- The Student’s t, since np > 5 and nq > 5.- The Student’s t, since np ≤ 5 and nq ≤ 5.- The standard normal, since np > 5 and nq > 5. (Selected)**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.)**Sketch the sampling distribution and show the area corresponding to the P-value.**(Four standard normal distribution curves are shown, each with a shaded area under the left tail.)**(d)** Based on your answers in parts (a) to (c), will you reject or fail to reject the null hypothesis? Are the data statistically significant at the 1% level?- At α = 0.01 level, we reject the null hypothesis and conclude the data are statistically significant.- At α = 0.01 level, we fail to reject the null hypothesis and conclude the data are not statistically significant.- At α = 0.10 level, we fail to reject the null hypothesis and conclude the data are statistically significant.- At α = 0.

collected data from 150 surveys ne nanaed out at a busy park located in the region. To continue the study into the drinking habits of adults, the researcher decides to collect data from adults working in "white collar" jobs to see whether their drinking habits are in the same proportion as the general public. The null hypothesis for this test is Ho: p = 0.26 and the alternative hypothesis is Ha: p<0.26. The researcher collected data from a random sample of 120 adults with "white collar" jobs of which 25 stated that they drank once a week or less in the last month. Assume that the conditions that must be met in order for us to use the N(0, 1) distribution as the sampling distribution are satisfied. Find the values of the sample proportion, p, the test statistic, and the p-value associated with the test statistic. Round all values to the nearest thousandth.

Looking at youth depression scores from a general sample of random children in the US, we want to determine if our sample is significantly different than the national average of scores of children with depression in the US.
