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.
X-3=66
x=69
69+41+(y-9)=180
110+y-9=180
101+y=180
y=79
