Marizza181 [45]

Given:

$\text{ Dimension = 3}\times5$

Sol:

Area of picture is:

$\begin{gathered} =\text{ length}\times\text{ Width} \\ \\ =15 \end{gathered}$

If the cost $10 per square inch then price of 15 square inch is:

$\begin{gathered} =15\times10 \\ \\ =150 \end{gathered}$

If the quadruple of dimension that mean:

$\begin{gathered} \text{ l ength = 4 length} \\ \\ Width\text{ = 4 width} \end{gathered}$

So area is:

$\begin{gathered} A=4\text{ length}\times4\text{ Width} \\ \\ A=4(15) \\ \\ A=60 \end{gathered}$

So price is:

$\begin{gathered} =60\times10 \\ \\ =600 \end{gathered}$

Suppose 58% of the population has a retirement account. If a random sample of size 570 is selected, what is the probability that

omeli [17]

Answer:

The probability that the proportion of persons with a retirement account will be less than 57%=31.561%

Step-by-step explanation:

We are given that

n=570

p=58%=0.58

We have to find the probability that the proportion of persons with a retirement account will be less than 57%.

q=1-p=1-0.58=0.42

By takin normal approximation to binomial then sampling distribution of sample proportion follow normal distribution.

Therefore, $\hat{p}\sim N(\mu,\sigma^2)$

$\mu_{\hat{p}}=p=0.58$

$\sigma_{\hat{p}}=\sqrt{\frac{p(1-p)}{n}}$

$\sigma_{\hat{p}}=\sqrt{\frac{0.58\times 0.42}{570}}$

$\sigma_{\hat{p}}=0.02067$

Now,

$P(\hat{p}$

$P(\hat{p}$ =31.561%

Hence, the probability that the proportion of persons with a retirement account will be less than 57%=31.561%
