Liam wants to estimate the percentage of people who lease a car. He surveys 240 individuals and finds that 54 lease a car. Find

scoundrel [369]

Answer:

$ME= z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}$

The confidence interval is 95% and the significance level is $\alpha=1-0.95=0.05$ and $\alpha/2 =0.025$ and the critical value would be:

$z_{\alpha/2}= 1.96$

And the margin of error would be:

$ME = 1.96 \sqrt{\frac{0.225 (1-0.225)}{240}}= 0.0528$

Step-by-step explanation:

We have the following info given:

$n =240$ the sample size selected

$X=54$ the number of people who lease a car

$\hat p =\frac{54}{240}= 0.225$ the estimated proportion of people who lease a car

The margin of error is given by:

$ME= z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}$

The confidence interval is 95% and the significance level is $\alpha=1-0.95=0.05$ and $\alpha/2 =0.025$ and the critical value would be:

$z_{\alpha/2}= 1.96$

And the margin of error would be:

$ME = 1.96 \sqrt{\frac{0.225 (1-0.225)}{240}}= 0.0528$

According to the empirical (69-95-99.7) rule, if a random variable z has a standard normal distribution, then approximately 95%

Dmitry_Shevchenko [17]

Using z-scores, it is found that the value of z is z = 1.96.

-----------------------------

Normal Probability Distribution

Problems of normal distributions can be solved using the z-score formula, which for a measure X, in a distribution with mean $\mu$ and standard deviation $\sigma$ , is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.
Each z-score has an associated p-value, which is the percentile.

The normal distribution is symmetric, which means that the middle 95% is between the <u>2.5th percentile and the 97.5th percentile</u>.
The 2.5th percentile is Z with a p-value of 0.025, thus Z = -1.96.
The 97.5th percentile is Z with a p-value of 0.975, thus Z = 1.96.
Thus, the value of Z is 1.96.
