The mean of the data set is 42.
<h3>What is Mean?</h3>
The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.
Given:
20, 32, 34, 36, 40, 42, 44, 48, 55, 65
Mean = 20+32+ 34+ 36+ 40+ 42+ 44+ 48+ 55+ 65/10
Mean = 416 / 10
Mean = 41.6
Mean = 42

Answer: 9.725 ≤ x ≤ 9.734
Step-by-step explanation:
We know that 9.73 is rounded, then we need to look at the next digit after the last one of 9.73, this would be the third digit after the decimal point.
We know that if this digit is smaller than 5, then we round down.
Then the largest number that can be rounded down to 9.73 is:
9.734
Now we want to find the smallest number that can be rounded up to 9.73
We know that if the next digit is 5 or bigger, then we round up.
Then the number 9.725 is rounded up to 9.73
And this is the smallest number that can be rounded up to 9.73
Then the error interval is:
9.725 ≤ x ≤ 9.734
