The days taken recovery in COVID patients is as following,

a) In BC the mean is 14 days with in a sample of 40 patients and population standard deviation of 1.2.

b) In Ontario, the mean is 16 days in a sample pf 42 patients and population std of 1.

Test hypothesis that mean of these samples are significantly different using critical value approach and alpa = 0.05 show all steps.

(hint z0.05/2 = 1.96)

Several years ago, a group of Honda Dealerships determined that the average amount of days automobiles stay on dealers' lots was equal to 22.1 days. They now believe that the mean time has changed and would like to test their belief at a significance level of 0.05. Results of a sample of 50 cars on various lots can be found in the file Honda Hypothesis Test. Use this information to answer the next several questions and ultimately decide whether or...

, "Opening up" is thought to improve individuals' mood following a tragic incident. A health psychologist is interested in its effect on HIV positive patients. The psychologist collected a sample of 17 HIV positive patients and asked them to talk about their HIV related issues ("open up") with their family. The psychologist assessed the patients' level of hopefulness afterwards and obtained a mean of 114.58 with a standard deviation of 4.92. The average hopefulness of HIV positive individuals is known...
