Consider using a z test to test  H0: p = 0.5.  Determine the P-value in each of the following situations. (Round your answers to four decimal places.) (a) Ha: p > 0.5, z = 1.43   (b) Ha: p < 0.5, z = −2.70   (c) Ha: p ≠ 0.5, z = −2.70   (d) Ha: p < 0.5, z = 0.23

Consider the following. (Give your answers correct to two decimal places.) (c) Calculate the value for the test statistic, ?2, for Ho: ? = 40.6, n = 30, s = 36.6.?2* = (d) Calculate the value for the test statistic, ?2, for Ho: ? = 11.7, n = 26, s2 = 161.

The test statistic for Ho: p = 0.75 versus HA: p > 0.75 is z = -3.05. What is the p-value for this test? Round to four decimal places. p-value

Solve A to C

The p-value is 0.0620, State the conclusion in terms of the claim and whether you would recommend shutting down the car factory with given p-value?

Harper collected data on students who make appointments to see their advisor to see how many failed to show up. The student records were divided into two groups: male (group 1) and female (group 2). A 93% confidnece interval for pi – P2 was found to be as follows: (0.03, 0.09) Interpret the endpoints of this interval in the context of this problem. Do not use the word "difference" in your answer.

13. Given P(A) = 0.17, P(B) = 0.42, and P(B|A) = 0.18, what is P(A and B)? Answer in decimal form. Round to 4 decimal places as needed.

Consider using a z test to test H0: p = 0.7. Determine the P-value in each of the following situations. (Round your answers to four decimal places.)   (a) Ha: p > 0.7, z = 1.44   (b) Ha: p < 0.7, z = −2.73   (c) Ha: p ≠ 0.7, z = −2.73

Refer to the accompanying data display that results from a sample of airport data speeds in Mbps. Complete parts (a) through (c) below. TInterval (13.046,22.15) X = 17.598 Sx = 16.01712719 n = 50 Click the icon to view a t distribution table. a. What is the number of degrees of freedom that should be used for finding the critical value t12? df = (Type a whole number.) b. Find the critical value t/2 corresponding to a 95% confidence level. ta12 = %3D (Round to two decimal places as needed.) c. Give a brief general description of the number of degrees of freedom. A. The number of degrees of freedom for a collection of sample data is the total number of sample values. B. The number of degrees of freedom for a collection of sample data is the number of sample values that can vary after certain restrictions have been imposed on all data values. C. The number of degrees of freedom for a collection of sample data is the number of sample values that are determined after certain restrictions…
