Company XYZ knows that replacement times for the quartz time pieces it produces are normally distributedwith a mean of 12.5 years and a standard deviation of 0.6 years.(a) Find the probability that a randomly selected quartz time piece will have a replacement time less than 11.2years. Give the probability rounded to 4 places after the decimal.PX 11.2 years) =(b) If the company wants to provide a warranty so that only 4.1% of the quartz time pieces will be replacedbefore the warranty expires, what is the time length of the warranty? Give the length in years, rounded to onedecimal place.Warranty length =years

Mean(µ) = 12.5Standard deviations (σ) = 0.6X ~ N (µ, σ )= N(12.5, 0.6)
