A supermarket has noticed a recent increase in the number of people venting their frustrations on social media about excessive waiting times during check-out. Even though they hire additional staff during peak shopping hours, they're not sure if they should hire even more staff during these peak hours or allocate some staff to non-peak hours. For a random selection of times during peak hours and another random selection of times during non-peak hours, the manager-on-duty goes to the check-out lanes and counts the number of people waiting in line. (a) Which type of hypothesis test should the supermarket use to determine if there is a difference in the number of people waiting in line during peak vs. non-peak hours?
(b) What is the meaning of a. Tyre. I. error. in. this. context? The supermarket concludes --- when in reality

yess

step-by-step explanation:

idk whyy this is happening, i cant even read my notification bc i keep getting errors

dont trust me im no expert these losers made me fail a test bro this sucks

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
