Consider the following hypothesis test.
The following results are from independent samples taken from two populations.
| Sample 1 | Sample 2 |
| n1=35 | n2=40 |
| xbar1=13.6 | xbar2=10.1 |
| s1=5.5 | s2=8.3 |
a. What is the value of the test statistic (to 2 decimals)?
b. What is the degrees of freedom for the t distribution (round the answer to the previous whole number)?
c. What is the p-value?
The area in the upper tail is - Select your answer -less than .005between .005 and .01between .01 and .025between .025 and .05between .05 and .10between .10 and .20greater than .20Item 3 ; two-tailed -value is - Select your answer -less than .005between .01 and .02between .02 and .05between .05 and .10between .10 and .20between .20 and .40greater than .40Item 4 .
d. At a=.01, what is your conclusion?
-value is - Select your answer -greater than or equal to 0.05, rejectgreater than 0.05, do not rejectless than or equal to 0.05, rejectless than 0.05, do not rejectequal to 0.05, rejectnot equal to 0.05, rejectItem 5
