7.     What percentage of a normal population is included in the quantity, “Plus or minus two standard deviations”? Provide your answer to two decimal places (e.g., 32.54%).

9.     How many standard deviations above and below the mean contains about 95% of a normal distribution?

Answer 1

(7) using empirical rule, we know that 95% of the data fall between 2 standard deviation from the mean

this means that 95.00% of the values found between plus or minus two standard deviation from the mean

So, answer is 95.00%

(9) This is just reverse question of the 7th question

Using empirical rule, we know that 95% of the data fall between 2 standard deviation from the mean

this means that 95.00% of the values found between plus or minus two standard deviation from the mean

So, we can say that 2 standard deviations above and below the mean contains about 95% of a normal distribution.
