Answer:
Answer for the question:
Bighorn sheep are beautiful wild animals found throughout the western United States. Let x be the age of a bighorn sheep (in years), and let y be the mortality rate (percent that die) for this age group. For example, x = 1, y = 14 means that 14% of the bighorn sheep between 1 and 2 years old died. A random sample of Arizona bighorn sheep gave the following information:x 1 2 3 4 5y 14 18.9 14.4 19.6 20.0 (a) Draw a scatter diagram. (3 points)(b) Find the equation of the least-squares line, and plot the line on the scatter diagram of part (a). (3 points)(c) Find the correlation coefficient r. Find the coefficient of determination . What percentage of variation in y is explained by the variation in x and the least squares model? (4 points)
is given in the attachment.
Explanation:
Answer:
Note: The full question is attached as picture below
a. Let X is denoted as company’s monthly demand, P(X=x) is denoted as the probability of the company’s monthly demand.
The expected value is obtained below:
E(X) = (300*0.20) + (400*0.30) + (500*0.35) + (600*0.15)
E(X) = 60+120+175+90
E(X) = 445
b. The expected value of the monthly demand is 445. The each unit demands the revenue to generate is $70 and their cost is $50.
The gain/loss of the company = (300*(70−50)) - (145*50)
The gain/loss of the company = (300*20) - (145*50)
The gain/loss of the company = 6,000 - 7,250
The gain/loss of the company =−$1,250(Loss)
Answer: $0
Explanation:
Forward contracts get their value from the cost and on December 1, there was no cost to Curtis as he Curtis had just signed the contract.
This means that the amount that should be recorded for the Forward Contract should be $0. Even though the contract is valued at $0, it will still need to be credited against the amount to be received to at least recognize that a forward contract was entered into.
