A pharmaceutical company claims that the average cold lasts an average of 8.4 days. They are using this as a basis to test new medicines designed to shorten the length of colds. A random sample of 106 people with colds, finds that on average their colds last 8.28 days. The population is normally distributed with a standard deviation of 0.9 days. At α=0.02, what type of test is this and can you support the company’s claim using the p-value?
| Claim is null, reject the null and cannot support claim as the p-value (0.170) is less than alpha (0.02) |
| Claim is null, fail to reject the null and support claim as the p-value (0.170) is greater than alpha (0.02) |
| Claim is alternative, fail to reject the null and support claim as the p-value (0.085) is less than alpha (0.02) |
| Claim is alternative, reject the null and cannot support claim as the p-value (0.085) is greater than alpha (0.02) |

A washing machine manufacturing company claims that an average
washing machine lasts 300 days. A researcher randomly selects 15
machines for testing. The sample machines last an average of 290
days with a standard deviation of 50 days. If the company's claim
is true, find the range of probability (area in
right tail from the table) that 15 randomly selected machines would
have an average life of no more than 290 days, in other words where
does your t-statistic lie...

8.8. A manufacturing company of light bulb claims that an
average light bulb lasts 500 days. A contractor randomly selects 30
bulbs for testing. The sampled bulbs last an average of 490 days,
with a standard deviation of 100 days. If the claim were true, what
is the probability that 30 randomly selected bulbs would have an
average life of no more than 490 days? [10]

A company that produces cell phones claims its standard phone
battery lasts longer on average than other batteries in the market.
To support this claim, the company publishes an ad reporting the
results of a recent experiment showing that under normal
usage,their batteries last at least 35 hours. To investigate this
claim, a consumer advocacy group asked the company for the raw
data. The company sends the group the following results: 35, 34,
32, 31, 34, 34, 32, 33, 35,...

A pharmaceutical company is testing a new cold medicine to
determine if the drug has side affects. To test the drug, 8
patients are given the drug and 9 patients are given a placebo
(sugar pill). The change in blood pressure after taking the pill
was as follows:
Given drug: 3 4 5 1 -2 3 5 6
Given placebo: 1 -1 2 7 2 3 0 3 4
Test to determine if the drug raises patients’ blood pressure

The owner of a new car dealership claims the average number of
days it takes his dealership to sell a Chevrolet Aveo is 50 days. A
random sample of 50 cars had a mean time on the dealer’s lot of 64
days. Assume the population standard deviation to be 7.0 days. Find
the 95% confidence interval estimate of the population mean.

Centron, a pharmaceutical company, produces an allergy relief
medication called Breezia. The company claims that the population
standard deviation of the duration of Breezia's allergy relief is
2.50 hours. A scientist with the FDA suspects, however, that the
standard deviation of the duration of Breezia's allergy relief is
greater than (less consistent than) what the company claims.
The scientist obtains a random sample of 24 adults with allergy
sensitivities, measures the duration of Breezia's allergy relief
for each person, and...
