Question

Determine the area under the standard normal curve that lies to the right of

left parenthesis a right parenthesis z equals 1.66 comma(a) z=1.66,

​(b)

z equals negative 1.26 commaz=−1.26,

​(c)

z equals 1.93 commaz=1.93,

and​ (d) z equals negative 1.37 .z=−1.37.

Answer 1

From the given information,

a)

Given z score = 1.66

From the right tailed z ( standard normal ) table , we have

P (z > 1.66 ) = 0.0485

b)

Given z score = - 1.26

From the right tailed z ( standard normal ) table, we have

P ( z > - 1.26 ) = 0.8962

c)

Given z score = 1.93

From the right tailed z ( standard normal ) table, we have

P ( z > 1.93 ) = 0.0268

d)

Given z score = - 1.37

From the right tailed z ( standard normal ) table, we have

P ( z > - 1.37 ) = 0.9147
