Please share a detailed solution: The life expectancy of TVs is normally distributed with a mean of three years and a standard deviation of ten months. Answer the questions that follow: What is the probability that a randomly selected TV will last more than 4 years? What percentage of TVs will last between four and five years? What percentage of TVs will last less than two years?

Step 1
2 Step 2: Find the probability that a randomly selected TV will last more than 4 years: Using a standard normal distribution table or calculator, the probability that Z is greater than 1.2 is approximately 0.1151. Step 3: Calculate the Z-scores for TVs lasting Show more…

A TV manufacturer knows that their TV's have a normally distributed lifespan, with a mean of 7.1 years, and standard deviation of 1.4 years. If a TV is picked at random, 3% of the time its life will be less than how many years? Give your answer to one decimal place.

Replacement times for TV sets are normally distributed with a mean of 8.2 years and a standard deviation of 1.1 years. Find the probability that a randomly selected TV will have a replacement time less than 5.0 years. (Round your answer to four decimal places.)

Life Span of a Television Part The life (in months) of a certain television part has a probability density function defined by $f(t)=\frac{1}{3} e^{-t / 3}$ Find the probability that a randomly selected component will last for the following lengths of time. (a) At most 9 months (b) Between 3 and 9 months (c) Find the cumulative distribution function for this random variable. (d) Use the answer from part (c) to find the probability that a randomly selected part will last no more than 6 months.
