Question

1) A sample of 61 small bags of the same brand of candies was
selected. Assume that the population distribution of bag weights is
normal. The weight of each bag was then recorded. The mean weight
was two ounces with a standard deviation of 0.12 ounces. The
population standard deviation is known to be 0.1 ounce.

a) (8 points) Construct a 90% confidence interval for the
population mean weight of the candies.

b) (2 points) Explain in a complete sentence what the confidence
interval means.

Answer #1

A sample of 18 small bags of the same brand of candies was
selected. Assume that the population distribution of bag weights is
normal. The weight of each bag was then recorded. The mean weight
was 3 ounces with a standard deviation of 0.12 ounces. The
population standard deviation is known to be 0.1 ounce.
NOTE: If you are using a Student's t-distribution, you may
assume that the underlying population is normally distributed. (In
general, you must first prove that...

A sample of 15 small bags of Skittles was selected. The mean
weight of the sample of bags was 2 ounces and the standard
deviation was 0.12 ounces. The population standard deviation is
known to be 0.1 ounces. (Assume the population distribution of bag
weights is normal)
a) Construct a 95% confidence interval estimating the true mean
weight of the candy bags. (4 decimal places
b) What is the margin of error for this confidence interval?
c) Interpret your confidence...

SunDrop Candies Inc claims that their 3 ounce bag of candies
contains over 90 pieces of candy.
A consumer group does not think this claim is accurate and obtains
a simple random sample of 26, 3 ounce, bags of the SunDrop Candies.
The number of candies in each bag is recorded.
Find a 95% confidence interval for the mean number of candies
contained in a 3 ounce bag of SunDrop Candies.
Here is the data:

You measure 33 watermelons' weights, and find they have a mean
weight of 61 ounces. Assume the population standard deviation is
14.9 ounces. Based on this, construct a 99% confidence interval for
the true population mean watermelon weight. Round your answers to
two decimal places. Enter your answers in the form: Sample Mean ±
Margin of Error

Potato chip bags are
labeled as containing 9 ounces of potato chips. To determine the
accuracy of this label, a simple random sample of 37 bags was
taken. The sample mean was 8.73 ounces and the sample standard
deviation was 0.18 ounces. Construct a 98 %
confidence interval for the population mean weight of bags of
potato chips.
a) Give the critical
value, ??.
b) Compute the
standard error, ?? ̅.
c) Calculate the
maximal margin of error, ?.
d)...

Bags of a certain brand of potato chips say that the net weight
of the contents is 35.6 grams. Assume that the standard deviation
of the individual bag weights is 5.2 grams. A quality control
engineer selects a random sample of 35 bags. The mean weight of
these 35 bags turns out to be 33.6 grams. If the mean and standard
deviation of individual bags is reported correctly, what is the
probability that a random sample of 35 bags has...

You measure 22 dogs' weights, and find they have a mean weight
of 42 ounces. Assume the population standard deviation is 2.2
ounces. Based on this, construct a 90% confidence interval for the
true population mean dog weight.

you measure 25 turtles weights, and find they have a mean weight
of 45 ounces. assume the population standard deviation is 4.2
ounces. Based on this, construct a 90% confidence interval for the
true population mean turtle weight.

A process produces bags of refined sugar. The weights
of the contents of these bags are normally distributed with a
standard deviation of 1.2 ounces. The contents of a random sample
of twenty five bags had a mean weight of 19.8 ounces. Find a 98%
confidence interval for the true mean weight for all bags of sugar
produced by the process. interpret the results
