Question
![Consider the following hypothesis test.
Họ: H 1 - 4 2 = 0
Hạ: H 1- 4 2 * 0
The following results are from independent samples taken from two populations.
Sample 1
Sample 2
ni = 35
n2 = 40
X1 = 13.6
X 2 = 10.1
s1 = 5.4
s2 = 8.9
a. What is the value of the test statistic (to 2 decimals)?
b. What is the degrees of freedom for the t distribution? (Round down your answer to the whole number)
c. What is the p-value? Use z-table.
The area in the upper tail is Select
]; two-tailed p-value is between Select
d. At a = .05, what is your conclusion?
p-value is Select
