Expert Solution
to test a relationship between GPA and frequency of attending classes,we will use method of significance of correlation coefficient as following types:-
first of we will collect data of GPA and frequency of attending classes for required sample size .here i take n= 6 .i.e. data GPA attendence of six students.
now first of all we have to find out the correlation between two variables GPA and frequency of attending classes as follows
hence there is enough evidence to conclude that there is a positive association between GPA and frequency of attending classes

Is there a linear correlation between students' high
school GPA and their current GPA( College GPA)? Here is the link to
our survey
1. Let's try to test this claim by using the survey.
Assume that alpha is 0.05.
2. What is the equation of the regression
line?
3. What is the best-predicted GPA if the high school
GPA is 3.5?

The average GPA of a random sample of 18 college students who
take evening classes was calculated to be 2.94 with a standard
deviation of 0.04. The average GPA of a random sample of 12 college
students who take daytime classes was calculated to be 2.89 with a
standard deviation of 0.05. Test the claim that the mean GPA of
night students is larger than the mean GPA of day students at the
.01 significance level.
