A researcher reports that mice that are first drastically restricted in their diets and then enriched with vitamins and protein will live an average of 40 months. If we assume that the life of such mice is normally distributed, with a standard deviation of 6.3 months, calculate the 40th percentile of the life time of these mice.
Answer using 4 decimals.

A research scientist reports that mice will live a mean of 40 months when their diets are sharply restricted and then enriched with vitamins and proteins. Assuming that the lifetimes of such mice are normally distributed with a standard deviation of 6.3 months, and the probability that a given mouse will live between 37 and 49 months.

A UCLA researcher claims that the average life span of mice can be extended by as much as 8 months when the calories in their diet are reduced by approximately 40% from the time they are weaned. The restricted diets are enriched to normal levels by vitamins and protein. Suppose that a random sample of 10 mice is fed a normal diet and has an average life span of 32.1 months with a standard deviation of 3.2 months, while a...

A researcher states that the life expectancy of mice can be extended by up to 25% when about 40% of the calories in their diet are reduced from the time they are weaned. The restricted diet is enriched to normal levels with vitamins and proteins. Assuming that from previous studies it is known that σ = 5.1 months, how many mice should be included in the sample to have 99% confidence that the expected half-life of the sample will be...
