It has been determined that the wait-time for computer support is normally distributed with a mean of 30 minutes and a standard deviation of 5 min. If 100 people call, how many would you expect to wait more than 30 min? (use logic here)

How do you calculate 15 percent of 40?
15/100 of 40 = 6
What is the normal IQ for a 4th grader when I was in 4th grade mine was 125 whats the normal?
100 is the average with a standard deviation of 15.
How do you calculate 15 percent of 6.00?
Multiply 6.00 by 15 and divide by 100. So 15% of 6.00 = 6.00*15/100 = 90.00/100 = 0.90
How do you calculate 15 percent of 250000?
Divide by 100 (cent means hundred, so 15 in every hundred) and multiply by 15. 250000 / 100 is 2500, x 15 is 37500

deviation 15 is better

Standard deviation is helpful in calculating?
Standard deviation is a calculation. It I used in statistical analysis of a group of data to determine the deviation (the difference) between one datum point and the average of the group.For instance, on Stanford-Binet IQ tests, the average (or, mean) score is 100, and the standard deviation is 15. 65% of people will be within a standard deviation of the mean and score between 85 and 115 (100-15 and 100+15), while 95% of people will be within 2 standard deviations (30 points) of the mean -- between 70 and 130.
Which is better a score of 92 on a test with a mean of 71 and a standard deviation of 15 or a score of 688 on a test with a mean of 493 and a standard deviation of 150?
score of 92
Which is more consistency arthematice mean is 110 and standard deviation is 25 and arthematic mean is 90 and standard deviation is 15?
The standard deviation is a number that tells you how scattered the data are centered about the arithmetic mean. The mean tells you nothing about the consistency of the data. The lower standard deviation dataset is less scattered and can be regarded as more consistent.
