answer:
given data,
p is 40%
probability is 40/100 = 0.40
n is 140
the Normal approximation to the Binomial distribution to be used.
the Expectation is np 43.2
the Variance is np(1 - p) 29.6
Standard deviation is 5.4222
the Z value for 38, z =(40-43.2)/5.4222
-3.2/5.4222
-0.590
-0.59 P( x < 40)
P( z < -0.59)
0.2779 Alternate answer: If we are use to the Binomial distribution,
P( x <38)
0.234
therefore 0.234
so fainally the answer is option e is correct answer
0.234 |
