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 and alternative hypotheses. Round to four decimal places when necessary.

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.

Step 4 of 5: Do we reject the null hypothesis or do we fail to reject the null hypothesis?

Step 5 of 5: What is the conclusion?

    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...

    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 48.42⁢mg 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?

    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 director of research and development is testing a new drug. She wants to know if there is evidence at the 0.025 level that the drug stays in the system for less than 393 minutes. For a sample of 17 patients, the mean time the drug stayed in the system was 387 minutes with a variance of 625. Assume the population distribution is approximately normal. Step 1 of 5: State the null and alternative hypotheses. Step 2 of 5: Find...

    Using traditional methods it takes 11.3 hours to receive a basic flying license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique on 20 students and observed that they had a mean of 11.6 hours with a standard deviation of 1.1. Is there evidence at the 0.05 level that the technique performs differently than the traditional method? Assume the population distribution is approximately normal. Step 1 of 5: State the null...

    A bolt manufacturer is very concerned about the consistency with which his machines produce bolts. The bolts should be 0.210.21 centimeters in diameter. The variance of the bolts should be 0.0250.025. A random sample of 2525 bolts has an average diameter of 0.2cm0.2⁢cm with a standard deviation of 0.05450.0545. Can the manufacturer conclude that the bolts vary from the required variance at α=0.05α=0.05 level? Step 1 of 5: State the hypotheses in terms of the standard deviation. Round the standard...
