Hypothesis Test for a Population Proportion
A well-known brokerage firm executive claimed that $80\mathrm{\%}$ of investors are currently confident of meeting their investment goals. An XYZ Investor Optimism Survey, conducted over a two week period, found that in a sample of 200 people, $74\mathrm{\%}$ of them said they are confident of meeting their goals.

Test the claim that the proportion of people who are confident is smaller than $80\mathrm{\%}$ at the 0.01 significance level.
The null and alternative hypothesis would be:
$$\begin{array}{cccccc}{H}_0:\mu =0.8& H_0:\mu \ge 0.8& H_0:p\le 0.8& H_0:p=0.8& H_0:\mu \le 0.8& H_0:p\ge 0.8\\ H_1:\mu \ne 0.8& H_1:\mu <0.8& H_1:p>0.8& H_1:p\ne 0.8& H_1:\mu >0.8& H_1:p<0.8\end{array}$$
The test is:
left-tailed two-tailed right-tailed $o^6/$
