Question

Think of each t-value that you see below as the calculated value of t from an hypothesis test. Thus, it is a test statistic. Now, for each test statistic, find the p-value as a range using Appendix D or the t-table in Moodle. (Directions: (1) Use the tail-area probabilities presented in the top row of the t-table and to the immediate right of "df" as your limits; (2) when recording your answers, let the first one be the smaller of the probabilities in the range and let the second one be the larger of the probabilities; and (3) if a limit is reported to two decimal places, record the 2 decimals; if it reported to 3 decimal places, record the 3 decimals.) p-value and (a) Right-tailed test t= 1.457, df.= 14 between (b) Left-tailed test t=-1.847, df. = 22 between and

Explanation / Answer

a) For p value use excel function

1-T.DIST(1.457,14,TRUE)

= 0.084

between 0.05 and 0.10

b) T.DIST(-1.847,22,TRUE)

= 0.039

between 0.01 and 0.05
