Answer:
The standard deviation of the sample is 0.0064.
Step-by-step explanation:
The standard deviation of a sample of length n of a population with standard deviation is given by the following formula:
In this problem, we have that:
61 randomly selected gas stations. This means that
The standard error of the mean is $0.05. This means that .
What is the standard deviation of the sample?
The standard deviation of the sample is 0.0064.
F = k x
15 = k *10
k = 1.5
check:
24 = 1.5 x
x = 16 sureenough
so 1.5 oz/inch
= 1/1.5 inches/oz = 2/3 = 0.6666.... in/oz
