Assume that a sample is used to estimate a population mean μ. find the margin of error m. e. that corresponds to a sample of size 14 with a mean of 19.4 and a standard deviation of 7.8 at a confidence level of 98%.

report me accurate to one decimal place because the sample statistics are presented with this accuracy.

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

41*67/2=1373.5

i just used a calculator

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).
