You wish to test the following claim (Ha) at a significance level of a = 0.02. H.:µ1 – µ2 =0 Ha:µ1 – P2 > 0 || You obtain the following two samples of data. Sample #2 Sample #1 61.3 63.5 47.7 51.2 52 39.2 59.7 53.3 54.7 51 54.2 45.5 55.6 46.6 65.3 33 54 48.4 46.6 49.2 65.8 58.6 53.4 49.4 54 54.7 67.7 41.4 47.1 46.1 34 55.4 57.7 55.5 40.7 54.2 Do not test the sample variances using Fcdf. Assume the sample variances are not equal and DO NOT POOL. What is the test statistic for this sample? (Report answer accurate to three decimal places.) test statistic = What is the p-value for this sample? For this calculation, use the degrees of freedom reported from the technology you are using. (Report answer accurate to four decimal places.) p-value = The p-value is... Oless than (or equal to) a Ogreater than a

Suppose 202 subjects are treated with a drug that is used to treat pain and 50 of them developed nausea. Use a 0.05 significance level to test the claim that more than 20 % of users develop nausea. A.dentify the null and alternative hypotheses for this test. B. Identify the​ P-value for this hypothesis test. C.Identify the conclusion for this hypothesis test.(reject or fail to reject and why?) D.Does the accuracy rate appear to be​ acceptable? (is there or is there not sufficent evidance to reject the claim and why?)

a. Identify the null and alternative hypotheses for this test. Choose the correct answer below. b. Identify the test statistic for this hypothesis test. c. The​ P-value for this hypothesis test is d. Identify the conclusion for this hypothesis test.

Passed Failed White Results from a civil servant exam are shown in the table to the right. Is there sufficient evidence to support the claim that the results from the test are discriminatory? Use a 0.05 significance level. 16 14 candidates Minority candidates 7 21 Determine the null and alternative hypotheses. O A. Ho: White and minority candidates do not have the same chance of passing the test. H4: White and minority candidates have the same chance of passing the test. B. Ho: A white candidate is more likely to pass the test than a minority candidate. H,:A white candidate is not more likely to pass the test than a minority candidate. Ho: A white candidate is not more likely to pass the test than a minority candidate. H,: A white candidate is more likely to pass the test than a minority candidate. D. Ho: White and minority candidates have the same chance of passing the test. H,: White and minority candidates do not have the same chance of passing the test. Determine the test…

Identify the​ P-value for this hypothesis test. d. Identify the conclusion for this hypothesis test. e. Do the results support the belief that 51.3% of newborn babies are​ boys?

6.   b. Test statistic = ? c. P-value = ?  d. Reject/Accept null hypothesis ?   -0.92 is wrong for the test statistic

What are the null and alternative​ hypotheses? A.H0​: The racial distribution is the same in at least two of the four regions. Ha​: The racial distribution is not the same in at least two of the four regions.   B. H0​: The racial distribution is the same in each of the four regions. Ha​: The racial distribution is not the same in each of the four regions.   C. H0​:The racial distribution is not the same in each of the four regions. Ha​:The racial distribution is the same in each of the four regions.   D. H0​: The racial distribution is not the same in at least two of the four regions.

Find the test statistic.   χ2= ​(Round to three decimal places as​ needed.)   Find the​ P-value.   P= ​(Round to three decimal places as​ needed.) Choose the correct conclusion below.     A. Do not reject H0. The data do not provide sufficient evidence that there is a difference.   B. Do not reject…

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?
