Answer:

C . $146.43

Step-by-step explanation:

lets use variables

dolls = d

remote cars = r

<h2><u>create an equation for the cost of dolls :</u></h2>

3 * 19.99 = <em>$59.97</em>

<h2><u>Create an equation for the cost of the remote cars</u></h2>

4 * 21.99 = $ 87.96

since there was a discount for each car bought, deduct from total cost

$87.96 - 4*3 =<em> $75.96</em>

<em />

now add the cost of the dolls and cars as well as the shipping cost :

59.97 + 75.96 + 10.5

= <u>$ 146.43</u>

<em />

Answer:

n=3.8416≅4

So Minimum Sample Size is 4

Step-by-step explanation:

In order to find the minimum sample size, the formula we use will be:

$n= \frac{Z^2*S^2}{E^2}$

Where:

n is sample size

Z is the distribution

S is the standard deviation

E is the Margin of error

S=3 ,E=3

For Z:

Alpha=1-0.95=0.05

Alpha/2=0.025=2.5%

From Cumulative Standard Distribution Table:

Z at Alpha/2 = 1.960

$n= \frac{1.960^2*3^2}{3^2}$

n=3.8416≅4

So Minimum Sample Size is 4
