You have a really annoying stapler that seems to randomly jam. On any given attempt to staple, itseems to independently jam 18.1% of the time. 360 attempts were made use the stapler.a) Find the mean and standard deviation for the number of jammed staples out of 360 attempts.Mean:Standard Deviation (rounded to 2 decimals):b) Does the normal approximation apply? Is the success / failure condition met (using a cutoff of 5)?NoYesc) Use the normal distribution (with continuity correction) to find the probability that your stapler will jammore than 79 times out of 360 attempts. Use the rounded standard deviation in your calculation.z-score (to 2 decimals) =probability (to 4 decimals, using the rounded z-score)

Given that n =360 , p =0.181 P (X >79 ) = ?

On the planet of Mercury, 4-year-olds average 3 hours a day unsupervised. Most of the unsupervised children live in rural areas, considered safe. Suppose that the standard deviation is 1.4 hours and the amount of time spent alone is normally distributed. We randomly survey one Mercurian 4-year-old living in a rural area. We are interested in the amount of time X the child spends alone per day.
