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

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

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

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

constants mean the stopped points or the points on a graph that nothing is changing, hope this
