Answer:
one i think
Step-by-step explanation:
As the normal distribution is symmetric the mean is (36 +
42) / 2 = 39
p(X < 42) = 1 - 0.063 = 0.937
From tables Φ (1.53) = 0.9370
From this time:
42 is 1.53 standard deviations above the mean
42 = 39 + 1.53s
1.53s = 3
Standard deviation is = 1.96
First, multiply 14 by 14 and then you can divide 25.90 by that number and that will be your answer
