Answer:
Hence the null hypothesis is not rejected.
We conclude that productivity objective (in dollars) is not better than $75,000 per employee.
Explanation:
Single sample t-test ( upper tail test)
[tex]H_0: \mu = 75000\\H_1: \mu > 75000[/tex]
N=20
Mean =75500
Sd=18968.117
[tex]t = \frac { (\bar x - \mu)} {\frac {s} {\sqrt{n}}}\\\\t = \frac{(75500-75000)}{\frac{18968.117}{\sqrt{20}}}\\t=0.1179[/tex]
DF= 20-1=19
Table value of t at 0.05 level of significance =1.7291
Calculated t=0.1179 < table value 1.7291
The null hypothesis is not rejected
We conclude that productivity objective (in dollars) is not better than $75,000 per employee
