Answer:
6280 mm squared
Step-by-step explanation:
To find the area Of a cylender we multiply pi times r squared times the height, and we can put pi as 3.14
the radius is 10 mm, and the height is 20 mm.
pug it in.
3.14 times 10 squared times 20.
3.14 time 100 time 20
314 times 20
6280 mm squared
Answer:
For this case a parameter represent the population data and for this case the parameter would be the true mean
who represent the amount of gasoline they used in the previous week

And the sample mean is an unbiased estimator of the true mean.
Step-by-step explanation:
For this case a parameter represent the population data and for this case the parameter would be the true mean
who represent the amount of gasoline they used in the previous week
And in order to estimate the parameter of interest we use a survey of n =3800 and the sample mean who represent an statistic is given by:

And we got:

And the sample mean is an unbiased estimator of the true mean.
