The ability to determine the age of some individuals can be difficult if there are not quality government records of birth. Bone growth takes place at the growth plates at the end of long bones. Once all growth plates fuse, growth stops, and an individual is considered a biological adult. The age at which growth plates fuse for males is approximately normally distributed with a mean of 18.7 years and a standard deviation of 16.1 months. (a) What is the probability a male's growth plates fuse after age 21? (Round to four decimal places as needed.)
Accrotime is a manufacturer of quartz crystal watches. Accrotime researchers have shown that the watches have an average life of 30 months before certain electronic components deteriorate, causing the watch to become unreliable. The standard deviation of watch lifetimes is 4 months, and the distribution of lifetimes is normal. (a) If Accrotime guarantees a full refund on any defective watch for 2 years after purchase, what percentage of total production will the company expect to replace? (Round your answer to two decimal places.) %(b) If Accrotime does not want to make refunds on more than 6% of the watches it makes, how long should the guarantee period be (to the nearest month)? months
The amount of daily sales of a Casetify in weekdays is approximately normally distributed with a mean of $4200 and a standard deviation of $720. (i) Calculate the probability that the amount of daily sales is between $2400 and $3192. (ii) Find the daily sales amount, k, for which 33% of daily sales amounts are below k. (iii) Calculate the probability that 9 randomly selected days have an average daily amount of sales above $4600.
A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 24 minutes. How large a sample should she take to estimate the mean time to within 3 minutes with 92% confidence? Sample Size =
Accrotime is a manufacturer of quartz crystal watches. Accrotime researchers have shown that the watches have an average life of 31 months before certain electronic components deteriorate, causing the watch to become unreliable. The standard deviation of watch lifetimes is 4 months, and the distribution of lifetimes is normal. (a) If Accrotime guarantees a full refund on any defective watch for 2 years after purchase, what percentage of total production will the company expect to replace? (Round your answer to two decimal places.) %(b) If Accrotime does not want to make refunds on more than 11% of the watches it makes, how long should the guarantee period be (to the nearest month)? months

Max Auto Sales is considering offering a special service contract that will cover the total cost of any service work required on leased vehicles. Service costs are approximately normally distributed with a mean of u and a standard deviation of RM 25. (i) If only 3% of the service cost is less than RM103, find the mean service cost. (ii) What is the probability that the service cost will be between RM130 and RM160 for a year? (iii) If the company offers the service contract to customers for a charge of RM180, what is the probability that any one customer’s service costs will exceed the contract price of RM180?
