A random sample of 836 births included 429 boys. Use a 0.01 significance level to test the claim that 51.2% of newborn babies are boys. Do the results support the belief that 51.2% of newbom babies are boys? Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. Ho: p=0.512 H,:p>0.512 O B. Ho: p=0.512 H,:p<0.512 OC. Ho: p=0.512 H,: p#0.512 O D. Ho: p#0.512 H,:p=0.512 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test.

An online poll​ asked: "Do you believe the Loch Ness monster​ exists?" Among 22185 responses, ​69%were​ "yes." Use a 0.10 significance level to test the claim that most people believe that the Loch Ness monster exists. How is the conclusion affected by the fact that Internet users who saw the question could decide whether to​ respond? Identify the null and alternative hypotheses for this test. Choose the correct answer below.     A. H0​: p>0.5 H1​: p=0.5   B. H0​: p=0.5 H1​: p<0.5   C. H0​: p=0.5 H1​: p>0.5   D.

The p-value for a hypothesis test turns out to be 0.03628. At a 9% level of significance, what is the proper decision? Reject Ho O Fail to reject Ho

The p-value for a hypothesis test turns out to be 0.00956. At a 3% level of significance, what is the proper decision? O Reject Ho O Fail to reject Ho

Assume a significance level of a 0.05 and use the given information to complete parts (a) and (b) below Original claim: The proportion of male golfers is more than 0.9 The hypothesis test results in a P-value of 0 056. a. State a conclusion about the null hypothesis. (Reject H, or fail to reject H, ) Choose the corect answer below. O A. Fal to reject H, because the P-value is less than a OB. Fal to reject H, because the P-value in greater than it OC. Reject H, because the P-value is less than a OD. Reject Hg because the P-value is greater than

Assume a significance level of a = 0.05 and use the given information to complete parts (a) and (b) below. Original claim: More than 58% of adults would erase all of their personal information online if they could. The hypothesis test results in a P-value of 0.1921. a. State a conclusion about the null hypothesis. (Reject Ho or fail to reject Ho.) Choose the correct answer below. O A. Reject Ho because the P-value is greater than a. O B. Reject Ho because the P-value is less than or equal to a. O C. Fail to reject Ho because the P-value is less than or equal to a. O D. Fail to reject Ho because the P-value is greater than a. b. Without using technical terms, state a final conclusion that addresses the original claim. Which of the following is the correct conclusion? O A. There is sufficient evidence to support the claim that the percentage of adults that would erase all of their personal information online if they could is more than 58%. O B. There is not sufficient evidence to support…

The percentage of complete passes is an important measure for a quarterback in the NFL. A particular quarterback has a career completion percentage of 55%. The quarterback got a new coach and then played a few games where he completed 48 of 100 passes. a. Specify the null and alternative hypotheses to determine whether the proportion of completed passes has decreased with the new coach. b. Calculate the value of the test statistic and the p-value. c. At the 5% significance level, can you conclude that the quarterback's completion percentage has decreased?  How do I solve this in excel?
