Hired you to analyze demand in 25 regional markets for a new product y, called angelica pickles. a statistical analysis of the demand in these markets shows (standard errors in parentheses): q = 250 - 10p + 6px + 0.25a + 0.04i (100) (3) (2) (0.1) (0.15) r2 = 90% standard error of the estimate = 75 here, qy is the market demand for product y, p is the price of y in dollars, a is dollars of advertising expenditures, px is the average price in dollars of another (unidentified) product, and i is dollars of household income. in a typical market, the price of y is $1,500, px is $500, advertising expenditures are $50,000, and disposable income per household is $45,000. the numbers in parentheses are standard errors of the coefficients. based on this information, do the following: a. calculate the expected level of demand for y. b. indicate the range within which actual demand is expected to fall with 95% confidence. c. interpret r2. d. test the significance of advertising (a), at α = 0.05.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts

10/60

step-by-step explanation:

if you divide 10 by 60 the answer is 0.166666 while if you divide or solve the other problems it equals 0.6

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
