Question

Use a y? tost to test the claim a <43 at the a=0.01 significance levol using sample statistics s = 40.9 and 21. Assume the population is normally distributed. Identify the null and alternative hypotheses. O A. Ho: > 43 Ho: 343 0 6 Ho: g = 43 H:02:43 OB. Mo: 0543 H: > 43 OD. Ho: 0243 H:<43 Identify the test statistic (Round to three decimal places as needed.) Identify the critical value(s). (Round to three decimal places as needed. Use a comma to separate answers as needed) Choose the correct conclusion below. O A. Reject Ho. There is enough evidence at the 1% level of significance to support the claim OB. Fail to reject Ho. There is not enough evidence at the 1% level of significance to support the claim O c. Reject Ho. There is not enough evidence at the 1% level of significance to support the claim OD.

Answer 1

we want to test, 9. Ho . ( 2,93 Ha : T <43 We have so = 43 sa 40.99 n-21, Test statistic, 2 2 2 - (n-1)S T² 20 * (40.9) (43)2 x² 18.094 > x² critical value at a=0-01 value x² .:8.260 fail do reject Ho . There is not enough evidence at the l. level of significance to Support the claim,
