<h2>The standard error of the mean is 7.56</h2>Step-by-step explanation:
The standard error of the mean is defined as the ratio of standard deviation to the square root of the sample size of a data. The standard error of the mean is mathematically expressed as shown below;
X is the standard error of the mean
is the standard deviation
n is the sample size.
Given;
On substitution into the formula we have;
X ≈ 7.56
Answer:
Step-by-step explanation:
In this case, the example is missing the negative sign.
This is an example of scientific notation, which is used to reduce a very large number into a short expression like: 0.000000005, which is reduced in the expression .
It's important to say that the negative sing in the exponent, indicates that all zeros that are being reduce, are placed at the right of the number. Also, to apply a correctly scientific notation, the number reduced should be between 0 and 10.
