A sample of 15 buttons is randomly selected and the following diameters are measured in inches. Give a point estimate for the population standard deviation. Round your answer to three decimal places. 1.33,1.25,1.22,1.27,1.39,1.34,1.33, 1.32,1.26,1.20,1.28,1.20,1.24,1.38, 1.31

The point estimate for the population standard deviation is of 0.061.

Step-by-step explanation:

The point estimate for the population standard deviation is the sample standard deviation.

Sample mean:

Sample standard deviation:

Square root of the sum of the difference squared of all these values (1.33, 1.25, 1.22,...) and the mean of 1.288, divided by 15 - 1 = 14.

Using a calculator, it is of:

The point estimate for the population standard deviation is of 0.061.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
