Answer:
By the Empirical Rule, 
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
The symbol of a standard deviation is 
. So
When plotting sample statistics on a control chart, 99.7% of the sample statistic values are expected to fall within plus/minus how many sigma?
By the Empirical Rule,

Answer: 10.5 minutes
Step-by-step explanation:
Given: Time taken to read each page of health book = 0.8 minutes
Time taken to take the test at the end = 5.5 minutes
Let x be the number of pages of book to read, then time taken to read pages and take the test is given by :-
If we read 6.25 pages, then time taken to read 6.25 pages and take the test is given by :-
1/3 because 4 to 12 can be written as 4/12 which can be simplified to 1/3
And 1/3 of 6 is two and if you reverse the process you would 4 into 12 three times and then find what goes into 6 three times with is 2
