A fruit processing unit produces canned fruit juice with a mean weight of 1 kg. and variance
of 0.020 kg. The cans are packed in boxes each containing 100 cans. Assuming that the
weights of individuals cans are statistically independent find the probability that the weight of
a box is between 99 kg. and 101.5 kg.

The manufacturer of a popular brand of TV knows from his past experience that the
probability of his TV set failing to work properly during the warranty period is 0.04. Find the
probability that in a sample of 25 sold TV sets selected at random, 6 or less TV sets will be
failing to work properly during the warranty period. Use both the binomial and Poisson rule
and compare the results.

Part A – Education and Income: Does it Pay to Stay in School?
In this activity you will investigate the relationship between educational attainment and income. The data will be obtained from the 2001 Census. Specifically, you will compare the percentage of people within a geographical area with college and university education to the average income within that area.
Finding the right table using Search Census
1. Start up E-STAT - at http://estat.statcan.ca 2. From the left tool bar click Search Census. 3. Under Census, select “2001 Census” and click “Go!” 4.

The number of gamma rays emitted per second by a certain
radioactive substance is a random variable having Poisson distribution
with
5.8. If a recording instrument becomes inoperative when
there are more than 12 rays per second, what is the probability that this
instrument becomes inoperative during any given secondHa 4

The following table shows the pesticide residue levels (ppb) in blood samples from
four populations of human subjects. Use the Kruskal-Wallis test to test at the
0:01 level of signi cance the null hypothesis that there is no di erence among the
populations with respect to median level of pesticide residue.

You are going to have a custom house built on a lot you inherited. You have been told the cost of construction will be approximately $120 per square foot. How would you go about determining how much you should pay? Would an algebraic equation help you in this situation? Why or Why not?
Q. If f, g is Reimann integrable on [a, b] then fg is reimann integrable on [a, b].
