Need help due friday

Ronch [10]

Answer:

C. f(x) = 40(1/4)^x

Step-by-step explanation:

Check all the options:

When x = 0

A. f(x) = 1/4(40)^x

f(x) = 1/4(40)^0

f(x) = 1/4(1)

f(x) = 1/4

When x = 0

B. f(x) = 1/2(40)^x

= 1/2(40)^0

= 1/2(1)

f(x) = 1/2

When x = 0

C. f(x) = 40(1/4)^x

= 40(1/4)^0

= 40(1)

= 40

When x = 0

D. f(x) = 4(1/3)^x

= 4(1/3)^0

= 4(1)

= 4

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
