Answer:
Step-by-step explanation:
For this case we have the following data:
23, 16, 21, 24, 34, 30, 28, 24, 26, 18, 23, 23, 36, 37, 49, 50, 51, 56, 46, 41, 54, 30, 40, and 31
We can calculate the sample mean with the following formula:
And replacing we got:
Then we can calculate the standard deviation with this formula:
And replacing we got:
And the sample size for this case is n =24. We can calculate the standard error with this formula:
And the median for this case since the sample size is 24 first we need to sort the data on increasing order and we got:
16 18 21 23 23 23 24 24 26 28 30 30 31 34 36 37 40 41 46 49 50 51 54 56
And for this case the median would be the average from the position 12 and 13 and we got:
