Complete Question:
A supervisor finds the mean number of miles that the employees in a department live from work. He finds x=2.9 and s=3.6. Which statement must be true?
z376 is within 1 standard deviation of the mean.
z37 is between 1 and 2 standard deviations of the mean.
z37 is between 2 and 3 standard deviations of the mean.
z37 is more than 3 standard deviations of the mean.
Answer:
z37 is between 2 and 3 standard deviations of the mean.
Explanation:
Standard deviation is a way of measuring of how much the value sample varies or disperses. A low standard deviation means that the values are near the mean value of the set, whereas a high standard deviation implies that the values are distributed over a wider range.
In reasonably average data sets, the values reflect about 68 per cent of the sample within 1 standard deviation from the mean; about 95 per cent in 2 standard deviations; and about 99.7 per cent within 3 standardized deviations.
Answer:
insurance company will pay $75 to Alfred.
Explanation:
given data
Actual cost of camera = $200
Alfred cost of camera = $150
Life expectancy = 6 years
solution
we get here first Remain life of camera that is
Remain life of camera = 6 years - 3 years
Remain life of camera = 3 years
and
now we get here current cost of the camera that is
current cost of camera = Alfred cost of camera × (Remain life of camera ÷ Life expectancy) ........................1
put here value and we get
Current cost of camera = $150 × 
Current cost of camera = $75
so that insurance company will pay $75 to Alfred.
