Noise levels at various area urban hospitals were measured in decibels. The mean of the noise levels in 99 corridors was 61.77 decibels, and the standard deviation of the population was 7.05. Find the upper boundary of the 95% confidence interval of the true mean. Only the final answer should be rounded-off to TWO decimal places.

In a survey, the mean weight of 1032 rats was calculated to be 132 gr. The standard deviation of the observation was found to be s=3 gr. Determine at least how many of the surveyed rats have a weight between 124.5 and 139.5 gr.
A study compared the weight loss of people on a low-fat diet versus people on a low-carb diet. In a sample of 100 obese people on a low-fat diet the sample mean weight loss as 7.6 pounds with a standard deviation of 3.2 pounds. In another sample of 120 obese people on a low-carb diet the sample mean weight loss was 6.7 pounds with a standard deviation of 3.9 pounds. Write down all formulas and state the hypothesisa) Test the hypothesis, at the 5% level of significance, that there is a difference in the mean weightloss of using the 2 different diets. b) What is the p-value?
