4. A public utility company assumes that annual water consumption (measured in cubic meters) of households with young families with children is normally distributed with mean 120 and standard deviation 55. Compute the probability that a randomly selected family has an annual water consumption of less than 80 cubic meters.

Assuming data re cholesterol indicated a mean total cholesterol level for adult persons 20 years of age and older in the United States was 190 mg/dl; with a known standard deviation of 30 mg/dl. The underlying population is normally distributed. 17. What is the probability that a randomly selected adult, ≥20 years of age will have a cholesterol level <170 mg/dl?
If the average length of all low-weight babies at the time of birth is known to be 36.5 centimeters with a standard deviation of 2.4 cm, use pnorm() to find the probability that the sample mean length is equivalent to the sample mean of our random sample or larger. random sample mean= 36.82

Assume that heights of U.S. men between 45 and 50 years of age are normally distributed with mean 70 inches and a standard deviation of 0.75 inches. Suppose a random sample of 49 men is selected. Find the probability that the average height of these 49 men is less than 69.8 inches.
Suppose that the annual rainfall in Waco can be modeled with a Normal distribution with a mean of 35.9 inches and a variance of 8.41. a) In 1999, the amount of rainfall in Waco was 20.48 inches, What is the probability of observing an annual rainfall of than 20,48 inches in Waco? What is the probability of having at least one year out of n=10 with a total rainfall amount of more than 40 inches? What assumptions must be made to answer this question?

Suppose that in a large population of women (aged 20 to 29-years-old) that the mean serum cholesterol level is 183 mg/dl and the standard deviation is 37. Find the probability that a sample of size 60 from this population will yield a mean cholesterol level. Greater than 190
29. A manufacturer knows that their items have a normally distributed lifespan, with a mean of 11.2 years, and standard deviation of 2.1 years. The 7% of items with the shortest lifespan will last less than how many years? (Show all work)
Nationally, the amount of debt from college student loans is exceeded only by mortgage debt and is a significant burden for many students after graduation. This photo shows the average student loan debt for a recent graduate of 4-year public colleges and universities in each state and Washington D.C. The distribution of the data can be approximated by a normal model with mean u = $28045 and standard deviation = $3604 a) use the normal model to determine the probability that the average student loan debt is more than $25000. b) use the normal model to determine the IQR of the average student loan debt.
