STEP 1
1. We are using the Student's t-distribution to find the P-value.
2. The test statistic and sample size are given.
3. The alternate hypothesis is specified for each part.
4. We will use a t-distribution table to find the range for the P-value.
STEP 2
1. Identify the degrees of freedom.
2. Use the t-distribution table to find the P-value range for part (a).
3. Use the t-distribution table to find the P-value range for part (b).
STEP 3
Calculate the degrees of freedom for part (a) and part (b).
For part (a), , so degrees of freedom .
For part (b), , so degrees of freedom .
STEP 4
For part (a), , , and .
Look up the critical values for with in the t-distribution table.
The P-value is between 0.10 and 0.20.
STEP 5
For part (b), , , and .
Look up the critical values for with in the t-distribution table.
The P-value is between 0.10 and 0.15.
The P-value ranges are:
- Part (a):
- Part (b):
