Agovernment agency conducted energy research on two different towns. the agency selected 12 homes from each town and recorded the number of kilowatt-hours used by the homes over a one-year period. the following statistical information was calculated from their findings.

jacobia cantorville
mean 11,178 11,613
median 11,653 11,572
mode 11,705 11,050
range 2,137 2,188

based on these samples, what generalization can be made?
a.
jacobia used more kilowatt-hours than cantorville.

b.
cantorville used more kilowatt-hours than jacobia.

c.
not enough information is provided to draw any of these conclusions.

d.
both towns used the same number of kilowatt-hours.

The answer is B. Cantorville used more kilowatt-hours than Jacobia.

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %
