- A consumer advocacy group suspects that a local supermarket’s 10 ounce packages of cheddar cheese actually weighs less than 10 ounces. The group took a random sample of 20 such packages and found that the mean weight for the sample was 9.955 ounces. The population is normally distributed with a standard deviation of .15 ounces. Test at the .01 level. ( Chap 9 ) (One tailed test)
- Use the either the p-value approach or the critical value approach to test the hypothesis that Ho; µ = 10 and H1; µ < 10. (Test at the .01 level) Show me your pvalues or zcrit values and state whether you accept or reject the Null Hypothesis.
Test at the .05 level. Show me your pvalues or zcrit values and state whether you accept or reject the Null Hypothesis

Suppose it is known from experience that the standard deviation
of the weight of 10-ounce packages of cookies is 0.20 ounces. To
check whether the true average is, on a given day, 10 ounces,
employees select a random sample of 36 packages and find that their
mean weight is x¯ = 9.45 ounces. Perform a two-tailed z-test on
this data, checking at the α = .01 significance level
State the null hypothesis in writing and in numbers

Suppose that a consumer advocacy group would like to conduct a
survey to find the proportion p of smartphone users that were happy
with their smartphone. The advocacy group took a random sample of
1,000 smartphone users and found that 400 were happy with their
smartphone. A 90% confidence interval for p is closest to:
a. (0.396, 0.404)
b. (0.375, 0.425)
c. (0.387, 0.413)
d. (0.390, 0.410)

Suppose a consumer advocacy group would like to conduct a survey
to find the proportion of consumers who bought the newest
generation of an MP3 player were happy with their purchase. Their
survey asked consumers if they were happy or unhappy with their
purchase. The responses indicated 28 out of 70 customers reported
being unhappy with their purchase. Compute a 90% confidence
interval for the population proportion of consumers who are happy
with their purchase.

A consumer advocacy group published a study of labeling of
seafood sold in three U.S. states. The study found that 15 of the
25 "red snapper" packages tested were a different kind of fish.
Assume that the study used a simple random sample. Complete parts a
through c below.
a) Are the conditions for creating a confidence interval
satisfied? Explain.
A. Yes, because the sample is a simple random sample, the
sample proportion is between 10% and 90%, and...

QUESTION 1
A consumer advocacy group compares the amount of nicotine in two
brands of cigarettes. A sample of 64 cigarettes from Brand A has an
average of 1.95 mg with a standard deviation of 0.24 mg. A sample
of 81 cigarettes from Brand B has an average of 1.85 mg and a
standard deviation of 0.22.
Suppose you want to estimate how much more nicotine is in Brand A
cigarettes in general using a 90% confidence interval.

A consumer advocacy group received a tip that an air
conditioning company has been charging female customers more than
male customers. The group's statistical expert decides examine this
question at the α=0.10α=0.10 level of significance, by looking at
the difference in mean charges between a random sample of female
customers and a random sample of male customers. Let μFμF represent
the average charges for female customers and μMμM represent the
average charges for male customers.(Round your results to three
decimal...
