3. (10 pts) If 132 of 200 male voters and 90 of 150 female voters support Archibald the Great to run for Chancellor of Nerdocrombesia, then construct a 99% confidence interval for the difference between the true
proportions p, -p, of male and female voters who support this candidate.
Note: Write your answer in interval notation (a, b) where each endpoint is rounded to 3 decimal places.
Using one of these formulas:

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
