Question 927869
Previously Posted
Ho: u = $15,000 (claim)
Ha: u ≠ $15,000
......
Sample: n = 15
 mean x-bar = 14,000 with a sample standard deviation of s = $2,000
.......
Test statistic: (14000-15000)/(2000/sqrt(15)) = -1.9365
p-value: p( z < -1.9365) = normalcdf(-100, -1.9365) = .0264
..........
.05 level of significance....
.0264 < .05, Reject Ho. 
The test results do NOT support the claim that  u = $15,000
