Binomial Probability Normal Probability

Find the indicated probabilities.
a. P (z > -0.89)
b. P (0.45 < z < 2.15)

Write the binomial probability as a normal probability using the continuity correction.
Binomial Probability Normal Probability
c. P ( x &#8804; 56) P ( x < ? )
d. P ( x = 69 ) P ( ? < x < ? )

Solution Preview

a) P[Z> -0.89] = P[-0.89< Z <infinity]

= P[-0.89< Z &#8804;0]+P[0< Z <infinity]

= P[0&#8804; Z <0.89]+P[0< ...

Solution Summary

The solution contains the determination of the binomial probability as a normal probability using the continuity correction.
