Answer:
We have a normal distribution with a mean of 267 days and a standard deviation of 15 days. To solve this proble we're going to need the help of a calculator.
a. The probability of a pregnancy lasting 309 days or longer is:
P(z>309) = 0.0026 or 0.26%
b. The lowest 4% is separeted by the 240.74 days. The probability of pregnancy lasting 240.74 days is 4%.
The linear equation is y = 4 + 0.5x
<h3>How to determine the equation?</h3>The points are given as: (-2,3) and (4,6)
The equation is then calculated using:
Substitute the known values
Evaluate
y = 0.5 *(x+2) + 3
Expand
y = 0.5x + 1 + 3
Evaluate the sum
y = 0.5x + 4
Rewrite as:
y = 4 + 0.5x
Hence, the equation is y = 4 + 0.5x
