The length of human pregnancies is approximately normal with mean μ=266 days and standard deviation σ=16 days. Complete pats (a) through (f). What is the probability that a randomly selected pregnancy lasts less than 260 days is approximately
Added by Levanté D.
Step 1
The z-score is calculated as: z = (X - μ) / σ where X is the value we're interested in (260 days), μ is the mean (266 days), and σ is the standard deviation (16 days). z = (260 - 266) / 16 Show more…
