In each of the following scenarios, determine if the data are paired.

a. We would like to know if Intel's stock and Southwest Airlines' stock have similar rates of return. To find out, we take a random simple of 50 days, and record Intel's and Southwest's stock on those same days.

b. We randomly sample 50 items from Target stores and note the price for each. Then we visit Walmart and collect t the price for each of those same 50 items.

c. A school board would like to determine whether there is a difference in average SAT scores fur students at one high school versus another high school in the district. To check, they take a simple random sample of 100 students from each high school.

negitive slope

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

part a. the differences are decreasing, so we know the sequence is not arithmetic. the ratios are constant (=3/4), so we know the sequence is geometric.

part b. from part a, we know the common ratio is 3/4, so each term is 3/4 of the one before. the initial term is the number of gallons at h=1.

g[h] = (3/4)·g[h-1]

g[1] = 384 . . . . initial value required for a recursive definition

part c. the general formula for a geometric sequence is

a[n] = a[1]·r^(n-1)

we have a[1] = 384, r = 3/4, and the term number given by h. the formula that follows is

g[h] = 384·(3/4)^(h-1)

part d. filling in the value and doing the arithmetic, we have

g[12] = 384·(3/4)^11 ≈ 384·0.042235136 ≈ 16.2183 . . gallons

part e. each gallon is 4 quarts, so

16.2183 gal × 4 qt/gal = 64.8732 qt
