Let x be a random variable that represents the level of glucose in the blood (milligrams per deciliter of blood) after a 12-hour fast. Assume that for people under 50 years old, x has a distribution that is approximately normal, with mean μ = 55 and estimated standard deviation σ = 41. A test result x < 40 is an indication of severe excess insulin, and medication is usually prescribed.

(a) What is the probability that, on a single test, x < 40? (Round your answer to four decimal places.)


(b) Suppose a doctor uses the average x for two tests taken about a week apart. What can we say about the probability distribution of x? Hint: See Theorem 7.1.

The probability distribution of x is not normal.The probability distribution of x is approximately normal with μ_x = 55 and σ_x = 41.    The probability distribution of x is approximately normal with μ_x = 55 and σ_x = 28.99.The probability distribution of x is approximately normal with μ_x = 55 and σ_x = 20.50.

What is the probability that x < 40? (Round your answer to four decimal places.)


(c) Repeat part (b) for n = 3 tests taken a week apart. (Round your answer to four decimal places.)


(d) Repeat part (b) for n = 5 tests taken a week apart. (Round your answer to four decimal places.)

Let x be a random variable that represents the level of glucose in the blood (milligrams per deciliter of blood) after a 12 hour fast. Assume that for people under 50 years old, x has a distribution that is approximately normal, with mean μ = 69 and estimated standard deviation σ = 44. A test result x < 40 is an indication of severe excess insulin, and medication is usually prescribed.

Blocher Company is evaluating the following methods of accounting for depreciation of long-lived assets and inventory:

Depreciation: straight-line; double-declining balance (DDB)
Inventory: first in, first out (FIFO); last in, first out (LIFO)

Assuming a deflationary environment (prices are falling), which of the following combinations will result in the highest net income in year 1?

Group of answer choices

A) DDB; FIFO.

B) Straight-line; LIFO.

C) Straight-line; FIFO.

A test is given and the average (μ_X) score out of 100 was only a 53.1, with a SD (σ_X) of 8.9. Assuming the grades followed a normal distribution, use the Z table or Excel and formulas to find the dividing line (test scores) between the A's, B's, C's, D's, and E's. Starting from the top, the teacher will give the highest 15% A's, the next 10% B's, the next 30% C's, the next 25% D's, and the bottom 20% will receive E's.
