suppose a data set consisting of exam scores has a lower
quartile Q1=60, a median m=75 and an upper quartile of Q3=85. the
scores on the exam range from 18 to 100. Without having the actual
scores available to you, which one of the following statements is
true?
a) the data set contains no suspected outliers
b) the data set contains suspected outliers only on its lower
end
c) the data set contains suspected outliers only on its upper
end...

State the number of friends (or connections) that you
have on Facebook (or Linkedin). In case you have more than 365
friends or connections, think of an alternative, smaller group of
friends or relatives. What is the chance that there are at least 2
people among your friends (or connections) with the same birthday
(same day, not same year)? Let's find out. Please respond with an
estimate of the probability that this will happen. This estimate
can be intuitive or...

Some customers of a retail chain have a store credit card that
earns them bonus gifts when they make purchases at the chain.
Currently, 22 customers are shopping in a store in this chain. Of
these, half already have a store credit card. If employees offer
store credit cards to 5 of these, what is the probability that all
of those chosen already have a card?
(b) A family of 5 is shopping in the store. Noting that

Create
a class called BirthYear. It should only have two member, both of
them arrays. One of type string called Names. The second of type
int called BirthYears. in your main class create a StudentBirthYear
object. Make sure both arrays are of the size 10. Add ten different
names and ten different birth years. Then display each name with
its birth year using only 1 for
loop.
(You
can display in a for loop as well as a foreach loop,...

(a) Obtain a frequency distribution for the test. (The number of
bins and intervals should be determined according to the rules in
the class slides).
(b) Draw a frequency histogram.
(c) Use the frequency distribution to compute the mean and the
median and variance. Are there any outliers in this data set?
(d) Plot the box plot of data based on the statistics you can...
