9) In 2015, the average math SAT score for students at South Hanover High School was 520. Five years later, a teacher wants to perform a hypothesis test to determine whether the average math SAT score of students at the school has changed since 2015. The hypotheses are: Ho:u= 520 H, : H 520 Suppose that the results of the sampling lead to acceptance of the null hypothesis. Classify that conclusion as a Type I Error, a Type Il Error, or a correct decision, if in fact the average math SAT score of students at the school is equal to 520.

A random sample of 857 births included 431 boys. Use 80.05 significance level to Tesla claim that 51.1% of newborn babies are boys. Did the results support the belief that 51.1% of newborn babies are boys? A. Identify the null and alternative hypotheses for this test.  B. Identify the test statistic for this hypothesis test. C.

Suppose 235 subjects are treated with a drug that is used to treat pain and 54 of them developed nausea. Use a 0.05 significance level to test the claim that more than 20​% of users develop nausea.The test statistic for this hypothesis test is .​(Round to two decimal places as​ needed.)

Suppose 245 subjects are treated with a drug that is used to treat pain and 50 of them developed nausea. Use a  0.01 significance level to test the claim that more than 20​% of users develop nausea.                                                                                                                                                                                                                                                   The test statistic for this hypothesis test is:   ​(Round to two decimal places as​ needed.) Part 3 Identify the​ P-value for this hypothesis test.   The​ P-value for this hypothesis test is:   ​(Round to three decimal places as​ needed.)

A random sample of 844 births included 431 boys. Use a 0.10 significance level to test the claim that 50.5​% of newborn babies are boys. Do the results support the belief that 50.5​% of newborn babies are​ boys?     Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. H0​: p=0.505 H1​: p<0.505   B. H0​: p=0.505 H1​: p≠0.505 Your answ   C. H0​: p≠0.505 H1​: p=0.505   D.

Classify the conclusion of the hypothesis test as a Type I error, a Type II error, or a correct decision. In 1995, the average math SAT score for students at one school was 486. Five years later, a teacher wants to perform a hypothesis test to determine whether olo the average math SAT score of students at the school has changed from the 1995 mean of 486. The hypotheses are: H,:u=486 Hu#486 Suppose that the results of the sampling lead to rejection of the null hypothesis. Classify that conclusion as a Type I error, a Type II error, or a correct decision, if in fact the average math SAT score of students at the school has changed from the 1995 mean of 486.
