Before every flight, the pilot must verify that the total
weight of the load is less than the maximum allowable load for the
aircraft. The aircraft can carry 36 passengers, and a flight has
fuel and baggage that allows for a total passenger load of 5,796
lb. The pilot sees that the plane is full and all passengers are
men. The aircraft will be overloaded if the mean weight of the
passengers is greater than 5,796 lbs / 36=161 lb. What is the
probability that the aircraft is overloaded? Should the pilot take
any action to correct for an overloaded aircraft? Assume that
weights of men are normally distributed with a mean of 181.1 lb and
a standard deviation of 37.3. The probability is approximately ___.
(Round to four decimal places as needed.

Part one:
Find an equation of the line that has an undefined slope and contains the point (-8,5). If possible, write the equation in slope-intercept form. Check that the ordered pair that represents the given point satisfies the equation.
The equation of the line is what?

Part two:
Find an equation of the line that contains the given point and is parallel to the given line. Use a graphing calculator to verify the result.
(-4,-7), 2x-3y = -24
The equation of the line is?

Part three:
Find an equation of the line that contains the given point and is parallel to the given line. Use a graphing calculator to verify the result.
(6,5), y = 2
The equation of the line is?

Part four:
Determine an equation of a line with a y-intercept of (0,8).

A survey found that women's heights are normally distributed
with mean 62.6 in. and standard deviation 2.9 in. The survey also
found that men's heights are normally distributed with mean 67.8
in. and standard deviation 3.3 in. Most of the live characters
employed at an amusement park have height requirements of a minimum
of 56 in. and a maximum of 64 in.
If the height requirements are changed to exclude only the
tallest 50% of men and the shortest 5% of men, what are the new
height requirements?
The new height requirements are a minimum of _____ inches and a
max of ______ inches

In a test of the effectiveness of garlic for lowering cholesterol, 42 subjects were treated with garlic in a processed tablet form. Cholesterol levels were measured before and after the treatment. The changes (before-after) in their levels of LDL cholesterol (in mg/dL) have a mean of 5.5 and a standard deviation of 17.6. Construct a 90% confidence interval estimate of the mean net change in LDL cholesterol after the garlic treatment. What does the confidence interval suggest about the effectiveness of garlic in reducing LDL cholesterol?

a) What is the confidence interval estimate of the population mean μ?
____mg/dL < μ < ___mg/dL

b) What does the confidence interval suggest about the effectiveness of the treatment?
A - The confidence interval limits do not contain 0, suggesting that the garlic treatment did not affect the LDL cholesterol levels.
B - The confidence interval limits do not contain 0, suggesting that the garlic treatment did affect the LDL cholesterol levels.
C - The confidence interval limits contain 0, suggesting that the garlic treatment did affect the LDL cholesterol levels.
D - The confidence interval limits contain 0, suggesting that the garlic treatment did not affect the LDL cholesterol levels.

The systolic blood pressure of adults in the USA is nearly
normally distributed with a mean of 122 and standard deviation of
19 .
Someone qualifies as having Stage 2 high blood pressure if their
systolic blood pressure is 160 or higher.
a. Around what percentage of adults in the USA have stage 2 high
blood pressure? Give your answer rounded to two decimal
places.
%
b. If you sampled 2000 people, how many would you expect to have
BP> 160? Give your answer to the nearest person. Note: I had a
bit of an issue encoding rounded answers, so try rounding both up
and down if there's an issue!

c. Stage 1 high BP is specified as systolic BP between 140 and 160.
What percentage of adults in the US qualify for stage 1?

d. Your doctor tells you you are in the 30th percentile for blood
pressure among US adults. What is your systolic BP? Round to 2
decimal places.

In a test of the effectiveness of garlic for
lowering cholesterol,
42
subjects were treated with garlic in a processed tablet form.
Cholesterol levels were measured before and after the treatment.
The changes
(before−after)
in their levels of LDL cholesterol (in mg/dL) have a mean
of
4.2
and a standard deviation of
15.3.
Construct a
99%
confidence interval estimate of the mean net change in LDL
cholesterol after the garlic treatment. What does the confidence
interval suggest about the effectiveness of garlic in reducing
LDLcholesterol?
