I do not agree because 3/4 is greater than 2/3 so you can not do 3/4-2/3
The estimated standard error for the sample is 6
Given,
Sample size, n = 36
Sample variance, = 1296
Standard deviation, s = √1296
= 36
Standard error, SE =
=
=
= 6
Concept
- Sample size is the number of participants or observations included in a study. It is denoted by ‘n’
- Sample variance is a measure of the degree to which the numbers in a list are spread out. It is denoted by ''
- Standard deviation is a measure of how dispersed the data is in relation to the mean. It is denoted by ‘s’

The first one A 7/2
You can just round up 6.75 -> 7 and 1.67->2
So what’s the question? What are we trying to find?
A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
<h3>What is a line?</h3>
A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.
