Question: Find the probability in each case a N = 3; n = 40; u = 74 and, sigma = 6; P( overline x <75.0)= b.

Find the probability in each case

a N = 3; n = 40; u = 74 and, sigma = 6; P( overline x <75.0)=

b. N = 80; n = 37n = 107 and, sigma = 3.52; P(106< overline x <106.4)=

c. N = 255; n = 100; u = 35.1 , and sigma = 4.89; P( overline x >= 36)=

d. N = 6000n = 20 = 122, and , sigma =13.5; P( overline x <=118)=
