Due to the heavy rains, all pallets of blocks have become wet, altering the weight of each block. It is desired to estimate the average weight of the wet blocks. A sample of 15 blocks is selected, and their weights in kilograms are recorded as follows:

45.8, 43.9, 46.2, 48.5, 47.2, 45.8, 49.1, 43.9, 47.6, 42.8, 46.5, 44.9, 46.8, 45.8, 44.6.

Estimate [tex]\mu[/tex], the average weight of all pallets of blocks, and determine a bound for the estimation error.

Answer :

Answer:

To find the estimated value we add all of them together then divide it by the amount of them

45.8+43.9+46.2+48.5+47.2+45.8+49.1+43.9+47.6+42.8+46.5+44.9+46.8+45.8 +44.6=689.4

now we divide it by 15 since there is 15 blocks so

689.4 divided by 15=45.96

so the average weight is 45.96
