Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a standard deviation of 1500 hours and a mean life span of 17,000 hours. If a monitor is selected at random, find the probability that the life span of the monitor will be more than 19,099 hours. Round your answer to four decimal places.

A manufacturer of computer monitors estimates that 4 percent of all the monitors manufactured have a screen defect. Let pd represent the population proportion of all monitors manufactured that have a screen defect. For the sampling distribution of the sample proportion for samples of size 100, μPˆd=0.04. Which of the following is the best interpretation of μPˆd=0.04 ? For all samples of size 100, the mean of all possible sample proportions of monitors manufactured that have a screen defect is...
The life spans of car batteries are normally distributed, with a mean of 62 months and a standard deviation of 5 months. (a) Find the probability that the life span of a randomly selected battery is less than 42 months. (b) Find the probability that the life span of a randomly selected battery is between 44 and 56 months. (c) What is the shortest life expectancy a car battery can have and still be in the top 5% of life...
minitab Can anyone help me with minitab question? The life spans of car batteries are normally distributed, with a mean of 44 months and a standard deviation of 5 months. A car battery is selected at random. Find the probability that the life span of the battery is less than 36 months. What is the shortest life expectancy a car battery can have and still be in the top 5% of life expectancies?
A quality control expert at Glotech computers wants to test their new monitors. The production manager claims they have a mean life of 75 months with a standard deviation of 5 months. If the claim is true, what is the probability that the mean monitor life would be less than 74.4 months in a sample of 85 monitors? Round your answer to four decimal places.
A random variable follows the normal probability distribution with a mean of 100 and a standard deviation of 10.
