The standard deviation of production has been 200 hours historically and is known to be normally distributed.a) Give a point estimate of lifespan of all production.b) Form an interval estimate for the students using a 99% confidence intervalc) Interpret the results you obtained in question }pd) Assuming the sigma of 200 was actually the standard deviation for the sample, recalculate the interval estimate. Discuss how this changed your result from that in part b.
