You wish to estimate the average weight of a mouse. You obtain 10 mice, sampled uniformly at random and with replacement from the mouse population. Their weights are 21; 23; 27; 19; 17; 18; 20; 15; 17; 22 grams respectively. (a) What is the best estimate for the average weight of a mouse, from this data

Respuesta :

Answer:

The best estimate for the average weight of a mouse, from this data is 19.9 grams.

Step-by-step explanation:

The best estime for the weight of a mouse from this data is the sum of all these weights divided by the number of mices.

10 mices

Their weights are 21; 23; 27; 19; 17; 18; 20; 15; 17; 22 grams

So

[tex]M = \frac{21+23+27+19+17+18+20+15+17+22}{10} = 19.9[/tex]

The best estimate for the average weight of a mouse, from this data is 19.9 grams.
