Question 1)
H0: 16.84 vs. HA: > 16.84
What is the test statistic forsample of size 26, mean 13.04, and standard deviation 1.30? Enter the test statistic with 2 decimal places.
Questions 2)
The results of sampling independent populations:
sample 1 from population 1
mean 1000
sample standard deviation 400
sample size 50
sample 2 from population 2
mean 1250
sample standard deviation 500
sample size 75
Test the H0: population 1 mean = population 2 mean at = 0.01. HA: population 1 mean population 2 mean. This is a two-tailed test with both a negative lower critical value and a positive upper critical values. Separate variances in assumed (Multiple choice question).
option A) Test statistic of -3.093 < critical values -1.29. HO rejected. Conclude difference of mean 0.
Option B) Test statistic of -65.28 > critical values -1.29. HO rejected. Conclude difference of mean = 0.
Option C) Test statistic of 65.28 > critical values -2.36. HO is not rejected. Conclude difference of mean = 0.
Option D) Test statistic of -3.09 < critical values -2.62. HO rejected. Conclude difference of mean 0.
