For the population of farm workers in New Zealand, suppose that weekly income has a distribution that is skewed right with a mean of p. = $500 (N. Z. dollars) and a standard deviation of o = $160. A survey of 100 farm workers is taken, including information on their weekly income. The probability that the mean weekly income of these 100 workers is between $480 and $520 is ＿ a...Normal cdf(480, 520, 0, 16)
b...normal cdf(480, 520, 500, 1)
c.normalcdf(520, 480, 50, 16)
d.normal cdf(480, 520, 500, 16)
e.1 - normalcdf(480, 520, 500, 16)

hard

step-by-step explanation:

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
