Answer:
Step-by-step explanation:
The lengths of human pregnancies are normally distributed with a mean of 268 day and a standard deviation of 15 days
From the information given,
mean, u =268
standard deviation, s = 15
x is number of days
For normal distribution,
z = (x-u)/s
Probability of x greater than or equal to 300 will be 1 - probability of x lesser than 300
z = (300-268)/15 =32/15 = 2.13
Looking at the normal distribution table, the value is 0.98341
Probability of x greater than or equal to 300 will be 1 -0.98341
= 0.01659
