5. The manufacturer of an antibiotic must ensure that each 5 mL dose contains 250 mg of the active ingredient. It is also essential that the variance of the amounts of active ingredient per dose be less than 0.1. For testing purposes, a random sample of 96 doses is taken, and the variance of the amounts of active ingredient per dose in the sample is found to be 0.09. Does this evidence support the claim that the variance is within the necessary bounds at the 0.01 level of significance?
(a) (3 points) State the null and alternative hypotheses H0 and Ha.
(b) (2 points) Identify which distribution to use for the test statistic. If applicable, calculate the number df of degrees of freedom; if not applicable, then say so.
(c) (2 points) Compute the value of the test statistic z, t, or χ 2 .
(d) (2 points) Compute the p-value associated to the test statistic.
(e) (1 point) Choose whether or not to reject the null hypothesis H0.

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...

1) Identify the rejection point(s) for the test of the following hypothesis: H0: mean = 10, Ha: mean != 10 Conducted on a sample size of 15, on a normally distributed population with unknown population variance, and a desired Type1 error probability (alpha) of 0.05. Hint: use the appropriate statistical function in your spreadsheet to determine the rejection point.

analyze the accuracy of the bottling process, the bottler takes a
random sample of 16 bottles with the following results. The data
are shown below.

In a research project, researchers collected demographic and health data from a sample of elderly residents in the community. To examine any possible gender differences in their sample, they want to see if the females and the males differ significantly on the education level (number of years of formal schooling). The researchers are not predicting any direction in the possible gender differences so the hypotheses should...
