This assignment is going to use the data set in R called
"airquality" that has 6 variables, as described below.
airquality:
A data frame with 154 observations on 6 variables.
[,1] Ozone numeric Ozone (ppb)
[,2] Solar.R numeric Solar R (lang)
[,3] Wind numeric Wind (mph)
[,4] Temp numeric Temperature (degrees F)
[,5] Month numeric Month (1--12)
[,6] Day numeric Day of month (1--31)
Using a significance level of 0.05, is there evidence to support
that the Temp can be...

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...

Below gives a data set for movie budgets, and domestic and
worldwide box office gross (all in millions) for several major
movies over time. Test the claim, at the � = 0.01 level, that the
domestic box office gross has a wider variation than the worldwide
box office gross. Movie Data Sheet,

Given the data to the left, which contains the age and the pulse
rate for 38 female patients. Using excel, TI, or statcrunch to find
and indicate the measures of central tendencies, the measures of
variations and the five-number summary of the pulse rates only.
Draw the box plot and the histogram for the pulse rates and the
scatter plot using both columns.
Write a brief conclusion including:
· What do the central tendencies tell you about the data, is...
