A drug used for treating cancer has potentially dangerous side effects if it is taken in doses higher than needed for treatment. The pharmaceutical company that manufactures the drug must be certain that the standard deviation of the drug content in each tablet is less than 0.1 mg. Fifteen tablets are analyzed to determine the amount of the drug in them. The sample mean is 20 mg, and the sample standard deviation is 0.08 mg.
Step 2 of 5:
If your test statistic was equal to 4.075, what would be your p-value? (Round to 3 decimal places.)
Step 3 of 5:
At the α = 0.01 level of significance, what would be the critical value of the test statistic? (Round to 2 decimal places.)
Step 4 of 5:
If the p-value is 0.009, what is your decision?

A drug, which is used for treating cancer, has potentially dangerous side effects if it is taken in doses which are larger than the required dosage for the treatment. The tablet should contain 56.02mg and the standard deviation should be 0.02. 12 tablets are randomly selected and the amount of drug in each tablet is measured. The sample has a mean of 56.025mg and a variance of 0.0001mg. Does the data suggest at α=0.05 that the tablets vary by less...

A drug, which is used for treating cancer, has potentially dangerous side effects if it is taken in doses which are larger than 46.33mg, the required dosage for the treatment. It is important that the variance of the amount of the active ingredient is 0.03. 10 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 0.0061mg. Does the data suggests at...

A drug which is used for treating high cholesterol has potentially dangerous side effects if it is taken at an improper dosage. The drug is manufactured at two different plants, plant A and plant B. A medical researcher believes that tablet A has a smaller variance in dosage than the variance in dosage from tablet B. The sample variance of a sample of 6 dosages of tablet A is 0.016. The sample variance of a sample of 20 dosages of...

The dosage of a drug in a particular tablet needs to be precise. It is essential that the tablets contain 56.04mg of the active ingredient with a variance of 0.03. A random sample of 25 tablets finds that the variance of the active ingredient is 0.026. 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 1 of 5: State the null...

A clinical trial was conducted to test the effectiveness of a drug used for treating insomnia in older subjects. After treatment with the drug, 22 subjects had a mean wake time of 94.6 min and a standard deviation of 41.5 min. Assume that the 22 sample values appear to be from a normally distributed population and construct a 90% confidence interval estimate of the standard deviation of the wake times for a population with the drug treatments. Does the result...

A clinical trial was conducted to test the effectiveness of a drug used for treating insomnia in older subjects. After treatment with the drug, 15 subjects had a mean wake time of 93.2 min and a standard deviation of 40.6 min. Assume that the 15 sample values appear to be from a normally distributed population and construct a 98% confidence interval estimate of the standard deviation of the wake times for a population with the drug treatments. Does the result...

2. A drug for treating acne possibly has a side effect of decreasing patients’ sense of self-worth. To test the impact of the acne drug, researchers gather 36 acne patients who are currently taking the acne medicine and give them a survey that measures their feelings of self-worth and self-concept. This sample has a mean self-worth and self-concept of 27. If the mean self-worth and self-concept for population of all people with acne is 32 with a standard deviation of...

In order for a new drug to be sold on the market, the variance of the active ingredient in each dose should be 0.02mg. A random sample of 25 tablets with a dosage strength of 48.42mg is taken. The variance of the active ingredient from this sample is found to be 0.0048. 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...

A certain drug is used to treat asthma. In a clinical trial of the drug, 19 of 250 treated subjects experienced headaches (based on data from the manufacturer). The accompanying calculator display shows results from a test of the claim that less than 8% of treated subjects experienced headaches. Use the normal distribution as an approximation to the binomial distribution and assume a 0.01 significance level to complete parts (a) through (e) below. 1-PropZTest prop<0.08 z = -0.233126202 p=0.4078317046 p=0.0760000000...
