You are constructing a 95% confidence interval of a sample space consisting of n = 40 values and a
population standard deviation of 2.6. the population appears to be skewed. determine whether a
margin of error should be calculated using a critical value of za/2, a critical value of ta/2, or neither.

im with everythinglos so yeahhhhh

step-by-step explanation:

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).
