What proportion are between 20 and 40 days old if there is Normal distribution with a mean of 28days and standard deviation of 8 days?
77.45%
What is the median of the prime numbers less than 40?
The median of the 12 primes less than 40 is 15.
How do the width and height of a normal distribution curve?
By standard practice, the normal distribution curve should be normalized so that the area under the curve is 1. This results in a height, at the mean, of about 0.4, i.e. the probability of a sample value being equal to the mean is 40 percent. The width of the normal distribution curve is infinite, as the tails are asymptotic to the X axis. It is easier to understand that the +/- one sigma area is 68.2 percent, the +/- two sigma area is 95.4 percent, and the +/- three sigma area is 99.6 percent.
What is the median of 20 28 24 28 40 39 31?
Median is 28
What is the median of 43 and 38?
It is 40.5, the number halfway between them. Median means "half of the numbers are above and half are below". With only two numbers we just split the difference. In this case the Median and the Mean are the same number - but this is not always the case. If our numbers were 43, 38, 33, 46 the Median would still be 40.5 but the Mean would be 40
