A merchant bought boxes oí chocolate and of candies of total mask 4000 g and total cos
Ona box of chocolate weighs 400 g and costs 2400 LL. and one box of candies weighs 200 g and
costs 800 LL.
1) Identify the unknowns, and then translate the given in a system of two equations with two
unknowns.
2) Soive the system to calculate the number of boxes of each kind.

Astudy found that the variance in the number of vehicles owned or leased by subscribers to a magazine is .094. assume a sample of 12 subscribers to another magazine provided the following data on the number of vehicles owned or leased: 1,1,1,0,3,2,1,1,2,1,0, and 1 a) compute the sample variance in the number of vehicles owned or leased by the subscribers (to 4 decimals). b)test the hypothesis to determine whether the variance in the number of vehicles owned or leased by subscribers of the other magazine differs from .calculate the value of the test statistic (to 3 decimals).
