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...

Use the data mtcars in R:
1. Describe the data in R. (e.g., how many variables, types of
variables).
2. Clean the data by deleting missing values.
3. Normalize the data/standardize the variables.
4. Determine the number of clusters.
5. Use k means cluster analysis.
6. Get cluster means.
7. Visualize the clustering result.

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,
