To test Ho: 4 = 20 versus He:<20, a simple random sample of size n = 19 is obtained from a population that is known to be normally distributed. Answer parts (a)-(d) Click here to view the t-Distribution Area in Right Tal. (8) If x=18.1 and 5 = 4, compute the best statistic - (Round to two decimal places as needed) (b) Draw a t-distribution with the area that represents the P-value shaded. Which of the following graphs shows the correct shaded region? ОА Ов. Ос. A. ni A
(c) Approximate the P-value. Choose the correct range for the P-value below. O A. 0.025<P value <0,05 OB 0.15 <P-value <0.20 OG 0,05 <P value <0.10 OD. 0.10 <P value <0.15 (a) the researcher decides to test this hypothesis at the a=0.05 level of significance, will the researcher reject the null hypothesis? OA. The researcher will not reject the null hypothesis since the P-value is not less than a OB. The researcher will reject the null hypothesis since the P-value is not less than a OC. The researcher will reject the null hypothesis since the P-value is less than a. OD. The researcher will not reject the null hypothesis since the P-value is less than a
