Question

A professor wants to know whether or not there is a difference in

Answer 1

Answer:

There is evidence since we have to apply a two-tailed test

p-value = 0.0212

Step-by-step explanation:

Given data:

α=0.05.

population std = 5.32

A) To test if there is difference in the comprehension of the lab based on test scores at α = 0.05.  = 5%

we will apply a two-tailed test  ( Null and alternate hypothesis test )

H0 : u1 = u2

Ha : u1 ≠ u2

there is evidence since we have to apply a two-tailed test

B ) Determine the P-value for the test

attached below  a detailed solution ( solved using excel )

Z- test : two sample for means

p-value = 0.0212
