Carbon monoxide (CO) emissions for a certain kind of car vary with mean 2.715 g/mi and standard deviation 0.8 g/mi. A company has
60 of these cars in its fleet. Let y represent the mean CO level for the company's fleet.
a) What's the approximate model for the distribution of y?
Explain.
Explain.
b) Estimate the probability that y is between 2.8 and 2.9 g/mi.
c) There is only a 10% chance that the fleet's mean CO level is greater than what value?

- Total plasma volume is important in determining the required plasma component in blood replacement therapy for a person undergoing surgery. Plasma volume is influenced by the overall health and physical activity of an individual. Suppose that a random sample of 50 male firefighters are tested and that they have a plasma volume sample mean of x = 37.5 ml/kg (milliliters plasma per kilogram body weight). Assume that ? = 7.20 ml/kg for the distribution of blood plasma.arrow_forwardThe length of a movie file that is available for streaming is modeled using the normal distribution shown belowarrow_forwardThe data represents the daily rainfall (in inches) for one month.

O A. No, although the frequencies start low, increase to some maximum, then decrease, the distribution is not symmetric. O B. No, the distribution is not symmetric and the frequencies do not start off low. O C. Yes, all of the requirements are met. O D. No, although the distribution is approximately symmetric, the frequencies do not start low, increase to some maximum frequency, then decrease.arrow_forward
