Answer:
a. The director is wrong: the lurking variable here is the severity of the blizzard. A more severe blizzard calls for more plows and keeps people at home, where they are more likely to make online purchases.
Explanation:
The director is correlating the number of snow plows on the road with the amount of online purchases - the <em>correlation </em>is high, but it doesn't mean that the increase on online purchases is <em>caused </em>by the number of snow plows on the road.
The question is: why would the number of snow plows on the road increase in the first place? Snow plows are sent out according to the amount of snow that has fallen, which means that the <em>lurking variable </em>that explains the increase in the number of snow plows and the amount of online purchases, is the severity of the blizzard in terms of how much snow has fallen. When the weather outside is too harsh or dangerous for people to go out, then it is most likely that they prefer online purchases. If the director were to analyze the correlation between the severity of the blizzard and the amount of online purchases, he would find a high correlation as well and in this case it would be the variable that actually explains the behavior of the consumers.
Remember that a lurking variable is the non-controlled variable that affects both the dependent and independent variables. In this case, there is nothing that the director can do about the severity of the blizzard besides perhaps increasing the stock whenever the severe blizzard season rolls around.
Answer:
$12,000
Explanation:
total preferred dividends per year = 1,200 x $50 x 5% = $3,000
since they were not paid during the past three years, and they are cumulative, the total preferred dividends = $3,000 x 4 = $12,000
common stock dividends = total dividends - accumulated preferred dividends = $25,000 - $12,000 = $13,000
cumulative preferred stocks that are not paid in the past, must be paid before any common dividends are paid

Answer:
$14
Explanation:
Sam parks his car for 8 hours, the first two hours cost $5 and he would pay $0.75 for every half hour after the first two hours . That means he would pay $1.50 for every hour after the first two hours.
He spent 6 hours extra. The total amount that would be paid = $1.50 × 6 = $9
He would pay a total of $9 for the 6 hours extra he parked his car.
The cost of parking for the 8 hours is = $9 + $5 = $14
