In R go to File< New Script (New Document on MAC) – A new script window will pop up. You should write all of your code in a script window and not directly in the console.

The R code can be uploaded directly into R by copying and pasting everything below R Code DA3.

Note: Any time you see # this means that R will not read what follows. I will use this to make comments about the following command.

R Code DA3 and DA#4:

# Upload Wine volume data using the [url removed, login to view] command. The [url removed, login to view]() command with will

# open a search window that will allow you to select the file.

# Make an appropriate visual display for the wine volumes data.

# Add color and other aesthetics if you like.

# See week 3 lessons

# Calculate the mean and standard deviation of the wine volumes data. mean() and sd()

# Perform a t test using the [url removed, login to view]() command.

# The format is [url removed, login to view](data, mu = mu_0) where data is a quantitative variable

# and mu_0 is the hypothesized mean.

#### PART IV Code #### YOU can try this if you are interested, but the output is already provided to you.

# creates a side by side boxplot with customized axes.

horizontal = TRUE, col = c("dodgerblue", "darkblue"), main = "Self-reported Daily Time Spent on Social Networking Sites

between International and Domestic ST314 Students",

xlab = "Estimated Time in Minutes per Day", axes = FALSE, ylab = "Students")

axis(1,at = NULL)

axis(2, at= c(1,2), labels = c("International", "Domestic"))

# Calculate means, sd and sample size by group

aggregate([url removed, login to view]~[url removed, login to view], data = [url removed, login to view], mean)

aggregate([url removed, login to view]~[url removed, login to view], data = [url removed, login to view], sd)

aggregate([url removed, login to view]~[url removed, login to view], data = [url removed, login to view], length)

# two sample t test
