A pharmaceutical company is evaluating its efficiency of its glucose control drug. The company believes that the drug controls glucose levels with the normal range of 80 to 115. A sample of 100 customers were found to have a mean of level of 102 with a standard deviation 12, can we conclude that the mean for this population is greater than 80 and less than 115, the sample is 100 and alpha is 0.5

A pharmaceutical company claims that its new drug reduces
systolic blood pressure. The systolic blood pressure (in
millimeters of mercury) for nine patients before taking the new
drug and 2 hours after taking the drug are shown in the table
below. Is there enough evidence to support the company's claim? Let
d = (blood pressure before taking new drug) − (blood pressure after
taking new drug). Use a significance level of α = 0.05 for the
test. Assume that the...

A pharmaceutical company claims that its new drug reduces
systolic blood pressure. The systolic blood pressure (in
millimeters of mercury) for nine patients before taking the new
drug and 2 hours after taking the drug are shown in the table
below. Using this data, find the 99% confidence interval for the
true difference in blood pressure for each patient after taking the
new drug. Assume that the blood pressures are normally distributed
for the population of patients both before and...

A pharmaceutical company claims that its new drug reduces
systolic blood pressure. The systolic blood pressure (in
millimeters of mercury) for nine patients before taking the new
drug and 22 hours after taking the drug are shown in the table
below. Is there enough evidence to support the company's claim?
Let d=(blood pressure before taking new drug)−(blood pressure
after taking new drug). Use a significance level of α=0.01 for the
test. Assume that the systolic blood pressure levels are normally...

A pharmaceutical company claims that its new drug reduces
systolic blood pressure. The systolic blood pressure (in
millimeters of mercury) for nine patients before taking the new
drug and 2 hours after taking the drug shown in the table below.
Using this data, find the 95 % confidence interval for the true
difference in blood pressure for each patient after taking the new
drug. Assume that the blood pressures are normally distributed for
the population of patients both before and...
