A box contains a large number of chips of two different colors:
red and blue, and it is desired to test the null hypothesis (H0)
that chips of the two colors are in equal proportions against the
alternative hypothesis (H1) that they are not in equal proportions.
Suppose that four chips are to be drawn at random from the box, and
H0 is to be rejected if and only if at least three of the chips
have the same color....

Suppose you want to determine whether the average values for
populations 1 and 2 are different, and you
randomly gather the following data.
sample 1
2, 11, 7, 8, 2, 5, 9, 1, 9, 1, 5, 8, 11, 2, 5, 5, 6, 9
sample 2
10, 12, 8, 12, 9, 12, 9, 7, 9, 10, 11, 10, 11, 10, 7, 8, 10,

Suppose we have a dataset called MYDATA. There are two
variables: COMPANY and SALARY. The variable COMPANY consists of
CO1, CO2, and CO3 and the variable SALARY includes the employees’
salaries from these three companies. Which code is most appropriate
SAS code to run ANOVA?
PROC UNIVARIATE DATA = MYDATA;
VAR COMPANY SALARY;
PROC UNIVARIATE DATA = MYDATA;
VAR COMPANY;
PROC GLM DATA=MYDATA;
CLASS COMPANY;
MODEL SALARY = COMPANY;
PROC GLM DATA=MYDATA;
CLASS COMPANY;
MODEL COMPANY = SALARY;

Problem Definition:
Problem: Given an array of integers find all pairs of
integers, a and b, where a – b is equal to a given
number.
For example, consider the following array and suppose we want to
find all pairs of integers a and b where a – b = 3
A = [10, 4, 6, 16, 1, 6, 12, 13]
Then your method should return the following pairs:
4, 1
15, 12
13, 10
A poor solution:
There are...
