A researcher claims that the life span of mice can be extended by as much as 25% when calories in their food are reduced by approximately 40% from the time they are weaned. The restricted diets are enriched to normal levels by vitamins and protein. Assuming that it is known from previous studies that o = 5.8 months. how many mice should be included in our sample it we wish to be 99% confident that the mean life span of the sample will be within 2 months of the population mean for all mice subjected to this reduced diet? You want to estimate the mean price of all the textbooks in the college bookstore. How many books must be included in your sample if you want to be 99% confident that the sample mean is within P5 of the population mean? 0 146 books 0 143 books 0 140 books 0 149 books
