An experimental research is conducted to test the effect of an anticoagulant drug on rats. A random sample of 6 rats is used in this study. Suppose the drug manufacturer claims that 85 % of the rats will be favourably affected by the drug.

(i) Apply a suitable probability model and compute the probability that none of the 6 experimental rats will be favourably affected by the drug.

(ii) Compute the probability that more than 2 experimental rats will be favourably affected by the drug.

(iii) Compute the probability that 2 experimental rats will not be favourably affected by the drug.

(iv) Calculate the mean number of experimental rats favourably affected by the drug.

A study was conducted to investigate the effect of a new drug in reducing systolic blood pressure in women. The sample average systolic blood pressure of 36 women who took the new drug was shown to be 24 mmHg with a standard deviation of 6 mmHG. The sample systolic blood pressure of 40 women who took the standard drug was measured to be 36 mmHG with a standard deviation of 4 mmHG. The claim is that the new drug will...

An experiment was conducted to test the effect of a new drug on a viral infection. After the infection was induced in 100 mice, the mice were randomly split into two groups of 50. The first group, the control group, received no treatment for the infection, and the second group received the drug. After a 30-day period, the proportions of survivors, p?1 and p?2, in the two groups were found to be 0.38 and 0.66, respectively. (a) Is there sufficient...

A food scientist conducted a study to determine the effect of the amino acid leucine on LAB (lactic acid bacteria) growth. Leucine was added at 0.38 mM to each of six batches of cucumber juice during fermentation. At 14 days after the start of the fermentation process, a sample of the juice from each batch was obtained and the dry weight of the LAB was measured. The samples contained a mean dry weight of 4.39 mg/ml with a variance of...
