The duration times of alcohol use for 12 different video games were recorded. The population mean \(\left( \mu \right) = 90{\rm{sec}}{\rm{.}}\)

For the true mean value\(\mu \), the hypothesis is stated as follows:

\(\begin{array}{l}{H_0}:\mu = 90\;({\rm{null}}\;{\rm{hypothesis}})\\{H_1}:\mu > 90\;({\rm{alternative}}\;{\rm{hypothesis}}\;{\rm{and}}\;{\rm{original}}\;{\rm{claim}})\end{array}\)

The following requirements need to be verified for conducting the test:

1. The given sample is selected randomly from the population.
2. The sample size is either larger than 30 or the population is distributed normally.

The normal Q-Q plot is sketched using the following steps:

1. Draw two axes, horizontal and vertical.
2. Mark z-scores corresponding to the observations on the change by means of scaling the axes.
3. Thus, the relevant graph along with a tentative line is shown below.

The points arenot close to the straight line; they deviate. Hence, this is not normally distributed.

Also, the sample is not specified to be selected by random selection.

Thus, the requirements are not satisfied.
