#9can you help me solve this problem step by step, An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 120 lb. and 161 lb. The new population of pilots has normally distributed weights with a mean of 126 lb. and a standard deviation of 29.8 lb. If a pilot is randomly selected, find the probability that his weigh is between 120 lb. and 1761 lb. A, if a pilot...

A)The drying time of a type of paint under specified test condition is known to be normally distributed with an assumed mean value of 75 and a standard deviation of 9. Test the hypothesis H0: µ=75 vs. Ha: µ<75 from a sample of 25 observations. How many standard deviations on the mean (standard error on the mean) away from the null value is the sample mean of 72.3?

The wait times to see a doctor at a large clinic are normally distributed with a mean of 68.2 minutes and a standard deviation of 14.8 minutes. If a simple random sample of 25 patients is selected, find the probability that the sample mean wait time is more than 75 minutes. Round to four decimal places.

Solve the problem. Suppose that replacement times for washing machines are normally distributed with a mean of 9.3 years and a standard deviation of 1.1 years. Find the probability that 70 randomly selected washing machines will have a mean replacement time less than 9.1 years. Write your answer as a decimal rounded to 4 places.

A paint company claims their paint will be completely dry within 45 minutes after application. Recently, customers have complained dryingtimes are longer than the claimed 45 minutes. A consumer advocate group takes a random sample of 25 paint specimens and records their drying times. The average drying time x is 50. Consider dryng time, for all test specimens, to be normally distributed with σ = 9. Suppose the claimed drying time is true, that is μ answer to four decimal...

The drying time of a certain type of paint under specified test conditions is known to be normally distributed with mean value 75 min and standard deviation 9 min. Chemists have proposed a new additive designed to decrease average drying time. It is believed that drying times with this additive will remain normally distributed with σ = 9. Because of the expense associated with the additive, evidence should strongly suggest an improvement in average drying time before such a conclusion...
