please include a final concluding statement that reflects exactly what the questions is asking of and also include the units.

1. In a research area, there is an assumption that the average body temperature of teens is higher than the average human temperature (98.6 degrees Fahrenheit). The average body temperature of a simple random sample of 25 teens is found to be 98.9 degrees Fahrenheit.

Suppose the population standard deviation of teens is 0.6 degrees Fahrenheit, and assuming 95% confidence, can we accept or reject this hypothesis?

2. A bag of potato chips is packaged by weight. A total of 36 bags are purchased, weighed and the mean weight of these 36 bags is 10.75 ounces.Suppose that the standard deviation of the population of all such bags of chips is 0.6 ounces.The stated weight on all packages is 11 ounces.Set a level of significance at 0.01.

Is this hypothesis rejected or accepted?

3. The expected percentage of the number of pets students have in their homes is distributed; the given distribution for the student population of the United States is given in the table below (left).A random sample of 1,000 students from the Eastern United States resulted in the data in the table on theright(below).

At the 1% significance level, does it appear that the distribution "number of pets" of students in the Eastern United States is different from the distribution for the United States student population as a whole?
