Store A sells melons that weigh 22 pounds on average with a standard deviation of 2.5. Store B sells melons that weigh 18 pounds on average with a standard deviation 2 pounds. You take an SRS of 40
melons from store A and an SRS of 34 from store B.
(A) Find the mean of each sampling distribution.
(B) Would it be reasonable to use the standard deviation formula? Explain.
(C) Find standard deviation of each sampling distribution.
(D) How would you describe each distribution?
(E) How would you describe the distribution of difference in mean weight of samples from the two
stores?
(F) Find the mean and standard deviation of the difference in the weight of melons from stores A and B.
(G) How frequently do the mean weights of the melons exceed 5 pounds?

24+x=y

step-by-step explanation:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
