A set of data has a normal distribution with a mean of 47 and a standard deviation of 7. Find the percent of data within the following interval. less than 47
Solutions
Expert Solution
Solution :
Given that ,
mean = 
= 47
standard deviation = 
= 7
P(x < 47) = P[(x -
) /
< (47 - 47) / 7]
= P(z < 0)
= 0.5
percent = 0.05%

The standard normal distribution is a continuous distribution
with a mean of 0 and a standard deviation of 1. The following is
true:
About 68% of all outcomes lie within 1 St.Dev.
About 95% of all outcomes lie within 2 St.Devs.
About 99.7% of all outcomes lie within 3 St. Devs.
The probability/percentage/percentile for a normal distribution is
the area under the curve. You will ALWAYS BE CALCULATING OVER AN
INTERVAL.
Values outside of 2 St.Devs. are considered “unusual values.”...
