A quality control engineer wanted to estimate the mean weight, in oz, for a particular package of chocolate chip cookies. The engineer took repeated random samples of size 100 packages and estimated the mean and standard deviation of the sampling distribution to be 13 oz and 0.21 oz, respectively. Based on the estimates for the sampling distribution, what provides the best estimates of the population parameters?

step-by-step explanation:

(x) - (y) = (1 + 4i)

zero

step-by-step explanation:

f(2)= x-2

plug in the 2 in the "x"

f(2)=2-2

f(2)=0

answer: 4
