The area under the standard normal distribution between 15 a

The area under the standard normal distribution between -1.5 and 1.5 is

a. 0.1338

b. 0.1668

c. 0.4332

d. None of the above

Solution

sol) Area between -1.5 and 1.5 is

p(-1.5<x<0)=0.4332

p(0<x<1.5)=0.4332

Nowp(-1.5<x<1.5)=0.4332+0.4332=0.8664

ANswer is none of these
