Suppose that a certain brand of calculators claims to
have a 7% defect rate.
a. If we select 6 calculators at random, what is the probability
that two or fewer of them are defective? Round your answer to three
decimal places.

b. A researcher believes that the defect rate is
actually higher than what the company claims. She selects 500
calculators and finds that 41 of them are defective. At a
significance level of 10%, does the researcher have evidence to
support her claim? Perform the appropriate hypothesis test. Round
your sample statistic to three decimal places.

Suppose the manufacturer of a certain drug claims the adverse event rate of the drug is...
Suppose the manufacturer of a certain drug claims the adverse
event rate of the drug is 20% (ie. 20% of people who take the drug
have an adverse event), but you think the adverse event rate is
higher. (In fact, you think the adverse event rate is 30%.) So, you
want to do a study to show the adverse event rate is higher than
20%. If the adverse event rate is really 30% and you obtain a
sample of size...

The manufacturer of a certain brand of auto batteries claims
that the mean life of these batteries is 45 months. A consumer
protection agency that wants to check this claim took a random
sample of 24 such batteries and found that the mean life for this
sample is 43.15 months. The lives of all such batteries have a
normal distribution with the population standard deviation of 4.5
months.
Find the p-value for the test of hypothesis with the
alternative hypothesis...

Suppose that in a certain region of California, earthquakes
occur at the average rate of 7 per year.
(a) What is the probability that in exactly three of the next
eight years, no earthquakes occur?
(b) What is the **expect**ed number of years to wait until we
have a year with exactly 7 earthquakes?
(c) In the next century, how many years would you **expect** to
see with more than 10 earthquakes?

The manufacturer of a certain brand of pre-made hamburgers
claims that the mean fat content of its burgers is 12 grams.
Management is concerned that the true average fat content of the
burgers is higher than this amount. To investigate, they sample 20
burgers and find a mean fat content of 13.1 grams. Assuming that
the fat content of burgers is Normally distributed with a
population standard deviation of ? = 3.1 grams, is there evidence
that the true average...

The defect rate for data entry of insurance claims has
historically been about 1.00%. This exercise contains only parts
a, b, c, d, and e. a) If you wish to use a sample size of 200,
the 3-sigma control limits are: UCL Subscript pequals nothing
(enter your response as a number between 0 and 1, rounded to
three decimal places). LCL Subscript pequals nothing (enter your
response as a number between 0 and 1, rounded to three decimal
places). b)...

A certain brand of cereal claims that the mean sodium content
per serving is less than 235 mg and past research suggests that the
standard deviation is 10 mg. You find that a sample of 53 cereal
servings has a mean sodium content of 233 mg. Using a 0.10
significance level, what can you conclude about the brand’s
claim?
1) What type of hypothesis test is this?
2) State the hypotheses.
3) Calculate the value of the Test Statistic.

A certain brand of toothpaste, Colcrest, is advertised as being
preferred by 7 out of 10 dentists. Assume that this is true. A
simple random sample of 6 dentists is taken.
a. Calculate the probability that 4 or fewer of the 6 dentists
prefer Colcrest.
b. What is the average (or mean) number of dentists for this
sample of size 6 who prefer Colcrest? What is the standard
deviation?

Suppose the life time of a certain brand of light bulbs is
exponentially distributed with an average of 1000 hours.
a. What’s the probability that a new light bulb won’t be able
to reach this amount of time?
b. What’s the probability that a new light bulb will have a
life between 1000 and 2000 hours?
c. Given that a light bulb has been working for 1000 hours,
what’s the probability that it can work for another 2000 hours or...
A community college claims that the standard deviation in the cost of TI calculators is at...
A community college claims that the standard deviation in the
cost of TI calculators is at least $15. A simple random sample of
43 stores that sell TI calculators yielded a sample mean of $84 and
a sample standard deviation of $12 for the cost of TI calculators.
Does this data refute the claim made by the community college?
Perform a statistical test at the 5% significance level. You may
assume that the cost of TI calculators is normally distributed....
