Answer:
x = $11400
Step-by-step explanation:
Naomi is paid $190 per week plus 5.5% of her total sales in dollars, x, which can be represented by g ( x ) = 190 + 0.055 x.
And Josiah is paid $475 per week plus 3% of his total sales in dollars, x, which can be represented by f ( x ) = 475 + 0.03 x
Let the weekly pat for them are equal.
Then, g(x) = f(x)
⇒ 190 + 0.055 x = 475 + 0.03 x
⇒ 0.025 x = 285
⇒ x = $11400
Therefore, for the value of x = $11400, that will make their weekly pay the same. (Answer)

In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
The margin of error is:
25% of all adults had used the Internet for such a purpose
This means that 
95% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
What is the required sample size for the new study?
This is n for which M = 0.03. So
Rounding up:
The required sample size for the new study is 801.
