To test H₂: =20 versus H,: p<20, a simple random sample of size n=16 is obtained from a population that is known to be normally distributed Answer parts (a)-(d). (a) If x=18.4 and s=4.3, compute the test statistic. t=(Round to two decimal places as needed.) (b) Draw a 1-distribution with the area that represents the P-value shaded. Which of the following graphs shows the correct shaded region? OA COB. OC. A Q 1 (c) Approximate the P-value. Choose the correct range for the P-value below. OA 0.10

To test Ho: 20 versus H,: <20, a simple random sample of size n= 16 is obtained from a population that is known to be normally distributed. Answer parts (a)-(d). (a) If x= 18.4 and s=4.3, compute the test statistic. t= (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? OA OB. OC. A Q 3 A Q (c) Approximate the P-value. Choose the correct range for the P-value below. OA 0.10<P-value < 0.15 OB. 0,05 P-value <0.10 OC. 0.15<P-value <0.20 OD. 0.20<P-value <0.25 (d) If 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 not reject the null hypothesis since the P-value is less than a OD. The researcher will reject the null hypothesis since the P-value is less than a A Ma C
