PLEASE ANSWER ASAP. Consider the following hypothesis test.

H0:  u1 -  u2 ≤ 0
Ha:  u1 -  u2 > 0

The following results are for two independent samples taken from the two populations.

Sample 1    Sample 2
n 1 = 45    n 2 = 55
x 1 = 26.0    x 2 = 22.6
σ 1 = 5.4    σ 2 = 7.0
a.  What is the value of the test statistic (round to 2 decimals)?

b.  What is the p-value (round to 4 decimals)? Use z-table. Use z-value rounded to 2 decimal places.

c.  With  = .05, what is your hypothesis testing conclusion? p- value is (greater than 0.05, do not reject/ less than or equal to 0.05, reject) H0

 

Consider the following hypothesis test.
Ho: μι – μ2 < 0
Ha:
₂: μ₁ −μ₂ > 0
The following results are for two independent samples taken from the two populations.
a. What is the value of the test statistic (round to 2 decimals)?
Sample 1
n₁ =
45
c. With a = 0.05, what is your hypothesis testing conclusion?
p-value is - Select your answer -
✓ Ho
= 26.0
T1
01 = 5.4
Sample 2
n₂ = 55
*2 = 22.6
02 = 7.0
b. What is the p-value (round to 4 decimals)? Use z-value rounded to 2 decimal places.
