Suppose an automotive repair company wants to determine the current percentage of customers who keep up with regular vehicle mai

Nina [5.8K]

Answer: 1692

Step-by-step explanation:

Formula to find the sample size :

$n=p(1-p)(\dfrac{z_{\alpha/2}}{E})^2$

Given : Confidence level : $(1-\alpha)=0.90$

⇒ significance level = $\alpha= 0.10$

z-value for 90% confidence interval (using z-table)= $z_{\alpha/2}=1.645$

Prior estimate of the population proportion (p) of customers who keep up with regular vehicle maintenance is unknown.

Let we take p= 0.5

Margin of error : E= 2%=0.02

Now, the required sample size will be :

$n=0.5(1-0.5)(\dfrac{1.645}{0.02})^2$

Simplify , we get

$n=(0.25)(6765.0625)=1691.265625\approx1692$

Hence, the required sample size = 1692

Kelvin gave 2/7 of his money to James. As a result, Kelvin had $140 and James had $100 the end. How much did James have at first

kaheart [24]

Answer = $44

1. Divide $140 by 5/7. It will give us how much Kelvin had originally, which is $196
(I got 5/7 by doing 7/7 - 2/7)

2. Find 2/7 of 196 by multiplying them. This is 56....meaning that Kelvin gave James $56

3. Subtract 100 - 56 to find how much James had before this, which is $44.
