Andru [333]
The dimension of the document is 35 inches by 40 inches.
It is redrawn at a scale of 1 1/2 or 3/2 or 1.5
The dimension will be:
35 * 1.5 = 52.5 in
40 * 1.5 = 60 in

Then redrawn again at 1/4 or 0.25
52.5 * 0.25 = 13.125 in
60 * 0.25 = 15 in

So the final dimensions of the drawing is 13.125 in by 15 in

NeTakaya

Answer:

For this case a parameter represent the population data and for this case the parameter would be the true mean \mu who represent the amount of gasoline they used in the previous week

\bar X= \frac{\sum_{i=1}^n X_i}{3800} =11.75

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 \mu 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:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

And we got:

\bar X= \frac{\sum_{i=1}^n X_i}{3800} =11.75

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