ella [17]

ANSWER:

104

STEP-BY-STEP EXPLANATION:

Given:

Standard deviation (σ) = 700

Confidence level = 95%

Mean error (Eμ) = 135

We have for a confidence level of 95%:

$\begin{gathered} \alpha=100\%-95\%=5\%=0.05 \\ \\ \alpha\text{/2}=\frac{0.05}{2}=0.025 \\ \\ \text{ The corresponding Z value for \alpha/2 = 0.025 is as follows:} \\ \\ Z_{\alpha\text{/2}}=1.96 \end{gathered}$

Now, we calculate the minimum value of the sample size as follows:

$\begin{gathered} n=\left(\frac{Z_{\alpha\text{/2}}\cdot\sigma}{E}\right)^2 \\ \\ \text{ We replacing:} \\ \\ \:n=\left(\frac{1.96\cdot 700}{135}\right)^2 \\ \\ \:n=103.2858\cong104 \end{gathered}$

The minimum sample size needed is 104

The club currently have 25 members

Yolanda's club requires that 80% of the members be present for any vote. If at least 20 members must be present to have a vote, it means that 80% of the members in Yolanda's club is 20 members.

In order to determine the number of members in the club, use this formula:

Number of members in the club = least number of members that have to be present to vote / percentage of members that must be present to vote

least number of members that have to be present to vote = 20

percentage of people that must be present to vote = 80%

20 / 0.8 = 25 members
