Question 2 (Use "R Studio")

Northface makes two different down-fill jackets, SupremeHeat and ComfortHeat. SupremeHeat's fill is computed to be normally distributed with a mean of 6mm, and standard deviation 2 mm. Northface provides a 5-year warranty on SupremeHeat. But to last that much, the down-fill should be 4.7mm; otherwise the jacket is sold as ComfortHeat (3.5 year warranty).

a.What proportion of jackets are expected to be sold as SupremeHeat.

b.If Northface wants that 45% of the jackets produced should be sold as ComfortHeat (say per market demand), then what should be the down-fill threshold set as (formerly set as 4.7mm)?
