Consider the following hypothesis test.
H0: μ1 − μ2 = 0
Ha: μ1 − μ2 ≠ 0
The following results are from independent samples taken from two populations.
| Sample 1 | Sample 2 |
|---|---|
|
n1 = 35 |
n2 = 40 |
|
x1 = 13.6 |
x2 = 10.1 |
|
s1 = 5.9 |
s2 = 8.5 |
(a)
What is the value of the test statistic? (Use
x1 − x2.
Round your answer to three decimal places.)
(b)
What is the degrees of freedom for the t distribution? (Round your answer down to the nearest integer.)
(c)
What is the p-value? (Round your answer to four decimal places.)

following information.
n1=50n1=50, ¯x1=2.32x¯1=2.32, s1=0.68s1=0.68
n2=35n2=35, ¯x2=1.98x¯2=1.98, s2=0.38s2=0.38
For degrees of freedom, use the smaller of
(n1−1)(n1-1) and (n2−1)(n2-1)
tα2tα2 = tinv(α, df)
SE = sqrt((s1s1)^2 / n1n1 + (s2s2)^2 / n2n2)
E = tα2tα2 * SE
CI = (¯x1−¯x2)±E(x¯1-x¯2)±E
Rounded both solutions to 2 decimal places.
