Question

In order for a new drug to be sold on the market, the variance of the active ingredient in each dose should be 0.01mg. A random sample of 10 tablets with a dosage strength of 56.94mg is taken. The variance of the active ingredient from this sample is found to be 0.0072. Does the data suggests at α=0.01 that the variance of the drug in the tablets is less than the desired amount? Assume the population is normally distributed.

Step 2 of 5: Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer to three decimal places.

Step 3 of 5: Determine the value of the test statistic. Round your answer to three decimal places.

Answer #1

2) df = 10 - 1 = 9

Critical value = = 2.088

3) test statistic

= 6.48

In order for a new drug to be sold on the market, the variance
of the active ingredient in each dose should be 0.03mg. A random
sample of 25 tablets with a dosage strength of 56.57mg is taken.
The variance of the active ingredient from this sample is found to
be 0.0192.. Does the data suggests at α=0.005 that the variance of
the drug in the tablets is less than the desired amount? Assume the
population is normally distributed.

The dosage of a drug in a particular tablet needs to be precise.
It is essential that the tablets contain 59.21mg of the active
ingredient with a variance of 0.02. A random sample of 18 tablets
finds that the variance of the active ingredient is 0.0118. Does
the data suggests at α=0.025 that the variance of the drug in the
tablets is less than the desired amount? Assume the population is

A drug, which is used for treating cancer, has potentially
dangerous side effects if it is taken in doses which are larger
than 47.87mg, the required dosage for the treatment. It is
important that the variance of the amount of the active ingredient
is 0.04. 15 tablets are randomly selected and the amount of the
drug in each tablet is measured. It is determined that the variance
of the amount of active ingredient is 0.0008mg. Does the data
suggests at...
