Expert Solution

to determine the value of c for

P(−0.96≤Z≤c)=0.7963 we need to find the probability below Z<-0.96 which is calculated either by excel formula or by Z table shown below as:

The P(Z<-0.96) =0.1685

and P(−0.96≤Z≤c)= P(Z<c) -P(Z<-0.96)

=> 0.7963+0.1685 = P(Z<c)

=> P(Z<c)= 0.9648

Now we use the Z table and find out the Z value corresponding to the probability value which is:

c= 1.81
