To test Ho: H = 20 versus H,: u

To test Ho: p = 20 versus HI : < 20, a simple random sample opsize n = 19 is obtained from a population that is k.rown to be normally distributed. Answer parts (aHd). Click here to view the t-Distribution Area in Right Tail. (a) It x = 182 and s = 4, compute the test statistic. t = (Round to two decimal places as needed) (b) Draw a t-disthbution with the area that represents the P-value shade < iNhich of the followtng graphs shows mrrect shaded region? (c) Approximate the P-value. Choose the correct range for the P-value below. (d) If the researcher decides to test this hypothesis at the = 005 level of significance. will the researcher reject the null hypothesis? C) A. The researcher wilt reject the nutl hypothesis since the P-va'ue is not less than a. C) B. The researcher will reject the null hypothesis since the P-value is less than a. O C. The researcher will not reject the null hypothesis since the P-vatue is less than u. C) D. The researcher will not reject the null hypothesis since the P-value is not less than (1.
