Answer: Estimated standard error for the sample mean difference would be 1.
Step-by-step explanation:
Since we have given that
Mean of MD = 4.90
So, Sum of difference would be

S = 288
n = 9
We need to find the standard error for the sample mean differences.
Estimated standard error for the sampled mean difference would be

Hence, estimated standard error for the sample mean difference would be 1.
First we have to put the numbers in order
2,6,8,13,16,28,32 and mark the two middle numbers
divide each half into half again and mark the middle number, in this case
2,6,8,13,16,28,32
subtract the 28 from the 6 and get 22
thats the interquartile range
