Expert Answer
Hey, since there are multiple subparts posted, we will answer first four question. If you want any specific question to be answered then please submit that question only or specify the question number in your message.
(a)
The alternative hypothesis state no direction. Moreover, “≠” symbol is in alternative hypothesis. Hence, the test is two-tailed test.
(b)
Step-by-step procedure to obtain the value of z using MINITAB:
- Choose Graph > Probability Distribution Plot choose View Probability > OK.
- From Distribution, choose ‘Normal’ distribution.
- Click the Shaded Area
- Choose Probability and Both Tail for the region of the curve to shade.
- Enter the Probability value as 05.
- Click OK.
Output using the MINITAB software is given below:

Distribution Plot Normal, Mean 0, StDev=1 0.4 0.3 0.2 0.1 0.025 0.025 0.0 -1.960 1.960 0 X Density
From the output, the critical value is ±1.96.
The decision rule is,
If z<–1.96, then reject the null hypothesis H0 ...
