Question

In the United States, males between the ages of 40 and 49 eat on average 103.1 g of fat every day with a standard deviation of 4.32 g ("What we eat," 2012).

Assume that the amount of fat a person eats is normally distributed. a.) State the random variable.

b.) Find the probability that a man age 40-49 in the U.S. eats more than 110 g of fat every day.

c.) Find the probability that a man age 40-49 in the U.S. eats less than 93 g of fat every day.

d.) Find the probability that a man age 40-49 in the U.S. eats less than 65 g of fat every day.

e.) If a group of 25 men from this group to select, find the probability that this group will have the mean (amount of fat consumed) more than 105g of fat

Answer #1

E) Suppose that males between the ages of 40 and 49 eat on
average 104.7 g of fat every day with a standard deviation of 4.43
g. The amount of fat a person eats is not normally distributed but
it is relatively mound shaped.
Find the probability that a sample mean amount of daily fat
intake for 38 men age 40-59 is more than 98 g. Round to four
decimal places.
P(x̄ > 98) =
Find the probability that a...

The owner of a local golf course wants to examine the difference
between the average ages of males and females that play on the golf
course. Specifically, he wants to test if the average age of males
is different from the average age of females. If the owner conducts
a hypothesis test for two independent samples and calculates a
p-value of 0.3318, what is the appropriate conclusion? Label males
as group 1 and females as group 2.

A professor selects a random sample of 50 Missouri adults (ages
18-64) and observes each of them for a day, recording the amount of
time that they spend engaging in physical activity (sports or
exercise). Suppose that, unknown to the professor, Missourians in
this age group average 17 minutes of physical activity per day with
a standard deviation of 12 minutes.
A: Find the probability that the mean of the professor’s sample
will be 15 minutes or more
B:There is...

The average American man consumes 10 grams of sodium each day.
Suppose that the sodium consumption of American men is normally
distributed with a standard deviation of 8 grams.. Let X = the
amount of sodium consumed. Round all numeric answers to 4 decimal
places where possible.
What is the distribution of X? X ~ N(,)
b. Find the probability that a randomly selected American man is
select and he consumes less than 11 grams of sodium per day.

Cholesterol is a type of fat found in the blood. It is measured
as a concentration: the number of milligrams of cholesterol found
per deciliter of blood (mg/dL). A high level of total cholesterol
in the bloodstream increases risk for heart disease. For this
problem, assume cholesterol in men and women follows a normal
distribution, and that “adult man” and “adult...
