For the following normal distribution answer the below quest

For the following normal distribution answer the below questions.

For the above curve, if this were a STANDARD Normal Distribution what would the mean be?  

If this were a STANDARD Normal Distribution what would the standard deviation be?  

Using this chart, if you had the height of 1000 3-year old children and they were normally distributed,

how many children would be between the average height and two standard deviations above average?  

Solution

For a standard normal distribution the mean is 0.

If this were a STANDARD Normal Distribution then the sd is 1.

Using the empirical rule it can be stated that 95% of the data would be between the average height and two standard deviations above average.
