The length of human pregnancies is approximately normal with mean mu equals 266 daysμ=266 days and standard deviation of 16 days how long is 5%
Added by Jose Miguel P.
Step 1
- Mean (μ) = 266 days - Standard deviation (σ) = 16 days - We want to find the length of pregnancy corresponding to the lowest 5% (i.e., the 5th percentile). Show more…

The lengths of human pregnancies are approximately normally distributed with a mean μ=266days and standard deviation σ=16. What is the probability that a randomly selected pregnancy lasts within 10 days of the mean? Round answer to 4 decimal places. please write out each step.

9. [ 8 points ] The lengths of human pregnancies are approximately normally distributed, with mean μ = 266 days and standard deviation σ = 16 days. (a) What proportion of pregnancies lasts at least 270 days? (b) Determine the minimum length of human pregnancies that are in the longest 5% of all human pregnancies.
