An incubation period is a time between when you contract a virus and when your symptoms start. Assume that the population of incubation periods for a novel coronavirus has population standard deviation of 2.4 days. By surveying randomly selected local hospitals, a researcher was able to obtain a sample of incubation periods of 40 patients with the average and the standard deviation of the data respectively 8.3 days and 2.91 days. At 10% significance level, test the claim that the average incubation period of the novel coronavirus is different from 6 days.

Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD. A random sample of 59 women between the ages of 41 and 45 with no major health problems were studied. The women were classified into one of two groups based upon their level of exercise activity: walking women and sedentary women. The 39 women who walked regularly had a mean BMD of 5.96 with a standard deviation of 1.22. The 20 women who are sedentary had a mean BMD of 4.41 with a standard deviation of 1.02. Which of the following inference procedures could be used to estimate the difference in the mean BMD for these two types of women
Volunteers who had developed a cold within the previous 24 hours were randomized to take either zinc or placebo lozenges every 2 to 3 hours until their cold symptoms were gone. Twenty-five participants took zinc lozenges, and 23 participants took placebo lozenges. For the placebo group, the mean overall duration of symptoms was x, 7.7 days, and the standard deviation was 1.4 days.

An incubation period is a time between when you contract a virus and when your symptoms start. Assume that the population of incubation periods for a novel coronavirus has an unknown population standard deviation. By surveying randomly selected local hospitals, a researcher was able to obtain a sample of incubation periods of 40 patients with the average of the data of 9 days and the standard deviation of 3 days. At 10% significance level, test the claim that the average incubation period of the novel coronavirus is different from 7 days.

A study of snow in Wyoming has a mean thickness of 68cm. A random sample of 12 snow piles in Washington has a mean sample thickness of 64.5cm and a stand. dev. of 7.9cm. Let's say the thickness has a normal distribution and we use an a=10% level of significance to test that the mean thickness of snow in Washington is less than Wyoming's snow thickness. What is the null and alternate hypothesis? How do we find the critical value and test statistic? We also need to make a decision about the null hypothesis using the test statistic and the traditional method then summarize a final conclusion.
