P(70 sxs 110) b) What are the mean and standard deviation of this distribution? (Type an integer or decimal rounded to three decimal places as needed.) b) The mean of this distribution is (Type an integer or decimal rounded to two decimal places as needed) The standard deviation of this distribution is (Type an integer or decimal rounded to two decimal places as needed.)

Explanation / Answer

here for normal distribution paramter a=40 and b=140

a) P(70<X<110)=(110-70)/(b-a) =(110-70)/(140-40)=40/100=0.4

b) mean =(a+b)/2 =(40+140)/2 =90

c) std deviation =(b-a)/(12)1/2 =28.87
