B)226mg<μ<234mg C)225mg<μ<233mg
D)225mg<μ<234mg

A laboratory tested 89 chicken eggs and found that the mean
amount of cholesterol was 192 milligrams. Assume that sigma equals

mean cholesterol content, mu, of all such eggs. Round to one
decimal place.
A. 189.3 to 194.7 milligrams B. 188.8 to 195.2 milligrams C.
188.2 to 195.8 milligrams D. 187.8 to 196.2 milligrams
Part 2:
Thirty randomly selected students took the calculus final. If
the sample mean score was...

A lab tested 99 chicken eggs and found that the average amount
of cholesterol was 217 milligrams, sd= 20 milligrams. construct a
97% confidence interval for the true mean cholesterol content, u,
of all those eggs

Find a confidence interval for estimating the population μ.
A laboratory tested 74 chicken eggs and found that the mean
amount of cholesterol was 238 milligrams with milligrams O=16.6.
Construct a 95% confidence interval for the true mean cholesterol
content, μ, of all such eggs

The cholesterol content of large chicken eggs is normally
distributed with a mean of 200 milligrams and a standard deviation
of 15 milligrams.
How many milligrams of cholesterol is in an egg if 33% of the
eggs have higher cholesterol content than the egg? Label a sketch
of the distribution, corresponding shaded areas, and documented
calculator commands.

The cholesterol content of large chicken eggs is normally
distributed with a mean of 187 milligrams and standard deviation 15
milligrams.
Use this information to answer the below by filling in the
blanks.
a. What is the probability one
of these eggs is between 186 and 200?
b. Seventy-five percent of these eggs have
cholesterol content less than ______

Use the given degree of confidence and sample data to
construct a confidence interval for the population mean
µ. Assume that the population has a normal
distribution.
A laboratory tested twelve chicken eggs and found that the mean
amount of cholesterol was 239 milligrams with s = 13.3 milligrams.
Construct a 95 percent confidence interval for the true mean
cholesterol content of all such eggs.
Group of answer choices
(230.4, 247.6)
(230.5, 247.5)
(230.6, 247.4)
(232.1, 245.9)

The cholesterol content of large chicken eggs is normally
distributed with a mean of 187 milligrams and standard deviation 15
milligrams. Use this information to answer the questions below.
Round your answer to two decimal places.
a. What is the probability one of these eggs is between 186 and
200?
b. Suppose six eggs are randomly chosen from this population of
eggs. What is the probability the average milligrams of cholesterol
of the sample be less than 200 milligrams?
c....

Use the given degree of confidence and sample data to construct
a confidence interval for the population standard deviation Assume
that the population has a normal distribution.
A laboratory tested seventy-one chicken eggs and found that the
mean amount of cholesterol was 215milligrams with s =12.1
milligrams. Construct a 90% confidence interval for the true
standard deviation of cholesterol content of all such eggs.
please show work or explain

Use the given degree of confidence and sample data to construct
a confidence interval for the population mean μ. Assume that the
population has a normal distribution. A laboratory tested twelve
chicken eggs and found that the mean amount of cholesterol was 185
milligrams with s=17.6 milligrams. Construct a 95% confidence
interval for the true mean cholesterol content of all such
eggs.
A.173.7mg <μ <196.3mg
B.173.8mg <μ <196.2mg
C.175.9mg <μ <194.1mg
D.173.9mg <μ <196.1mg
