6. The physician-recommended dosage of a new medication is 14 mg. Actual administered doses vary slightly from dose to dose and are normally distributed with mean ?. A representative of a medical review board wishes to see if there is any evidence that the mean dosage is more than recommended and so intends to test the hypotheses: H0: ? ? 14 vs Ha: ? > 14 To do this, he selects 16 doses at random and determines the weight of each. He finds the sample mean to be 14.12. Assume the population standard deviation to be 0.24 mg. What decision would be made at the ? = 0.05 level of significance? A. p-value is 0.032; Reject H0. B. p-value is 0.977; Do not reject H0. C. p-value is 0.023; Reject H0. D. p-value is 0.023; Do not reject H0. E. p-value is 0.968; Do not reject H0.

Step 1
Substituting the given values, we get: z = (14.12 - 14) / (0.24/√16) = 2 Show more…

The physician-recommended dosage of a new medication is 14 mg. Actual administered doses vary slightly from dose to dose and are normally distributed with mean μ. A representative of a medical review board wishes to see if there is any evidence that the mean dosage is more than recommended and so intends to test the hypotheses: H0: μ ≤ 14 vs Ha: μ > 14 To do this, he selects 16 doses at random and determines the weight of each. He finds the sample mean to be 14.12. Assume the population standard deviation to be 0.24 mg. What decision would be made at the α = 0.05 level of significance? A. p-value is 0.032; Reject H0. B. p-value is 0.977; Do not reject H0. C. p-value is 0.023; Reject H0. D. p-value is 0.023; Do not reject H0. E. p-value is 0.968; Do not reject H0.

The physician-recommended dosage of a new medication is 14 mg. Actual administered doses vary slightly from dose to dose and are normally distributed with a mean. A representative of a medical review board wishes to see if there is any evidence that the mean dosage is more than recommended and so intends to test the hypotheses given below. H0: μ = 14, Ha: μ > 14. To do this, he selects 16 doses at random and determines the weight of each. He finds the sample mean to be 14.12 mg and the sample standard deviation to be s = 0.24 mg. Based on these data, test the hypotheses using a significance level of 0.05.
