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.
576 I hope this help cause I did this two years ago so I'm a little rusty but I think this is correct

so: -1 x -1 = 1
-7 x -7 = 49
Ans: 1/49
Hope this helps :)
The answer is choice 1 because when you divide 2 numbers with the same base and different exponents you subtract the second exponent from the first.
p^-m / p^-n = p^(-m - (-n))
CHOICE 1
Hope this helps
