0.3569 is the probability that they have a mean pregnancy between 266 days and 268 days.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 268 days
Standard Deviation, σ = 15 days
We are given that the distribution of lengths of pregnancies is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling =
P(pregnancy between 266 days and 268 days)
24*3.14= 75.36= 15.37 in^2 is your answer
help with rounding numbers:
four or less, let it rest ( 4 and less let the number be the same and change the numbers after it into zeros)
five or more, change the score. ( five and more change the number one up and change the numbers after it into zeros)
