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.

Which set of measurements can represent the lengths of a triangle's sides?
zepelin [54]
Triangle, not a triangle, not a triangle, triangle

Determining if three side lengths can make a triangle is easier than it looks. All you have to do is use the Triangle Inequality Theorem, which states that the sum of two side lengths of a triangle is always greater than the third side. If this is true for all three combinations of added side lengths, then you will have a triangle.[
