Question

Find the standard deviation of the sampling distribution of sample means using the given information. Round to one decimal place, if necessary.
μ=77 and σ=14; n=64

Answer 1

The standard deviation of the sampling distribution of sample means using the given information is 1.8

What does the mathematical term "rounding" mean?

Rounding is a method for estimating a specific number in a situation. To determine how to round a number, look at the next digit in the appropriate position; if it is less than 5, round down, and if it is greater than 5, round up. The precise rounding of decimal figures is referred to as "rounding decimals."

What are the guidelines for rounding off decimal numbers?

To locate the rounding digit, look at its right side.

If the right-side numbers are less than 5, consider them to be equal to zero.

The digit on the right is increased by one and the other digits are treated as zero if the right-side digits are greater than or equal to 5.

The population standard deviation divided by the square root of the sample size, or n, gives the standard deviation of the sampling distribution of sample means, or x, for any given population. Therefore:

For the provided data, the sampling distribution's standard deviation of sample means is $\frac{14}{\sqrt{64} }$, or 1.8.
