Answer:
Step-by-step explanation:
From the given information;
The null hypothesis & alternative hypothesis:

The test statistics can be computed as:




The p-value = 2(Z > 2.11) since this is a two-tailed test
The p-value = 2( 1 - Z < 2.11)
The p-value = 2 (1 -0.9826)
The p-value = 2 (0.0174)
The p-value = 0.0348
Decision Rule: To reject the
if the p-value is less than 
Conclusion: We fail to reject
and conclude that the population mean = 2, thus the machine is properly adjusted.
