<h3>Answer: 6.282</h3>
Explanation:
Refer to the table below. I've added a third row where I multiplied each x value with its corresponding frequency value f. We can refer to this row as the xf row.
Once we know the xf values, we add them up to get 245.
We'll then divide that result over the sum of the frequency values (add everything in the second row). The sum of the frequency values is 39.
So the mean is approximately: 245/39 = 6.282051 which rounds to 6.282
Notice that this mean value is fairly close to the x value which has the highest frequency.
Splitting up [0, 3] into equally-spaced subintervals of length
gives the partition
where the right endpoint of the -th subinterval is given by the sequence
for .
Then the definite integral is given by the infinite Riemann sum
