Question

Consider the following hypothesis test.
HO: 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 = 80 n 2 = 70
1 = 104 2 = 106
σ 1 = 8.4 σ 2 = 7.6

 

  1. What is the value of the test statistic? If required enter negative values as negative numbers (to 2 decimals).
  2. What is the p-value (to 4 decimals)? Use z-table.
  3. With  = .05, what is your hypothesis testing conclusion?
