H_0 Smaller companies in their region are and they spend at least 24 hours per week on the marketing of the these companies

H_1 There really is no growth for smaller firms in their area because the companies spend or less 24 hours per week on marketing.

In step 2:

Each test statistics meaning is calculated. Around two decimal places for your reply.

z=\frac{\bar{X}-\mu_{0}}{\frac{\sigma}{\sqrt{n}}}=\frac{23.2-24}{\frac{4.2}{\sqrt{88}}}=-1.787

In step 3:

Draw a start and write the decision.

Since it is observed that z=-1.787 < z_c=-1.64 it is then concluded that the null hypothesis is rejected.

Consequently we consider that small companies in their field may not expand, as they spend or less 24 hours per week on marketing.
