1. The
following data set is the number of hours that a sample of college
students
spent studying for a
test:
0,
0, 0 , 3, 3, 5, 6, 6, 8, 10, 12, 15
a)Find the 5-number summary for this data: Low,
Q1.Q2,Q3 High
b) Use the 5-number summary to make a
box-and-whisker plot for this set of data. Be sure to use a number
line with an appropriate scale.
c) Based on the box-and-whisker plot, is...

The
following data set contains the college GPA of a sample of ten
randomly selected UWG professors:
1.8, 2.1, 2.3, 2.5, 2.6, 3.2, 3.4, 3.7, 3.9, 4
A.) Construct a normal probability plot of the data set. Do
the GPA’s appear to be normally distributed? Yes or No.
B.) Find the critical t value that corresponds to a 90%
confidence level for the data rounded to 2 decimal places.
C.) Construct a 90% confidence interval for the mean GPA of...

Data Set A- 7,7,7,9,9,9,10
Data Set B- 4,6,6,6,8,9,9,9,10,10,10
Step 1
Create a bar graph that examines a variable or variables in
your data set.
Step 2
Find the sample mean, median (if it exists) mode for each set
of data
Next find the sample standard deviations for each set of
data
Create a box and whisker plot for each variable for each set
data
Eliminate any outliers from the samples. Redo part 1 for each
variable (if necessary, if not...

Use the data set 8, 10, 16, 18, 20, 22, 22, 24 for the next
problems. 1. What is the mean of the data set? 2. What is the
median of the data set? 3. What is the range of the data set? 4.
What is the mode of the data set? 5. What is the standard deviation
of the data set? 6. Create a box and whisker plot for the data
set.
Consider the following set of sample data, and find the
