Suppose a brewery has a filling machine that fills 12 ounce bottles of beer. It is known that the amount of beer poured by this filling machine follows a normal distribution with a mean of 12.23 ounces and a standard deviation of 0.04 ounce. Find the probability that the bottle contains fewer than 12.13

Suppose that the walking step lengths of adults are normally distributed with a mean of 2.4 feet and a standard deviation of 0.3 feet. A sample of 34 step lengths is taken. Find the probability that the mean of the sample taken is more than 2.5 feet. Your answer should be from the cumulative normal distribution table.
a). Your company is considering submitting a bid on a major project. You determine that the expected completion time for the project is 100 days, and that the standard deviation of the expected completion time is 8 days. (It is assumed that the normal distribution applies here.) You wish to set the project completion date in your bid such that there is an 80% chance that you will be able to complete the project by the date you have set. What due date should you set? (Note: fractional dates are allowed.) b.) What is the probability that the project described above is done within 90 days?
The time that college students spend studying per week have a distribution that skewed to the right with a mean of 8.4 hours and a standard deviation of 2.7 hours. Find the probability that the mean time spent studying per week for a random sample of 40 is less than 7.5 hours.
It is known that the amount of beer poured by a machine at a brewery has follows a normal distribution with a mean of 12.29 ounces and a standard deviation of 0.04 ounce. Find the probability that the bottle contains between 12.19 and 12.25 ounces.
The average amount of money spent for lunch per person in the college cafeteria is $6.24 and the standard deviation is $2.05. Suppose that 6 randomly selected lunch patrons are observed. Assume the distribution of money spent is normal, and round all answers to 4 decimal places where possible.For the group of 6 patrons, find the probability that the average lunch cost is between $6.2647 and $7.3532.
Assume the girths (circumferences) of five year old oak trees in the Jefferson National Forest are normally distributed with a mean of 18.5 inches and a standard deviation of 3.5 inches. USING THE EMPIRICAL RULE, find the probability that a randomly selected 5 year old oak tree from the Jefferson National Forest will have a girth between 15 and 25.5 inches. Draw a diagram.
An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 181 lb. The new population of pilots has normally distributed weights with a mean of 136 lband a standard deviation of 29.6 lb. b. If 38 different pilots are randomly selected, find the probability that their mean weight is between 130 lb and 181 lb.
