One-Sample T Test Null Hypothesis: ?= 6.5 Alternative Hyp: H 6.5 Variable Mean SE T DF Study Time 7.5180 0.4811 2.20 19 0.0282 Cases Included 20 Notice that the alternative hypothesis that was used does not match the test we desire. Give the p-value that should be used if we wish to conduct a one- tailed test O p=.0282 p 0564 P-.0141 p-9718 80 p - F6 F9 F4 FS F7 F8Explanation / Answer
from the data given we see p-value =0.0282 is for two tail test , to get p-value for one tail test we simply need to divide it by 2. So p-value for one tail is =0.0141
option c is correct
