1) Examine the following three lines of R code. Write a comment above each (after the#) describing what each line is doing. Each comment should be maximum one line. You don't
need to rewrite the code in your answer booklet.
#
mang. df <- data. frame(read. csv("MangroveData10Nov2015.csv", header=T))
#
z. value <- (1.0 - mean(mang. df$height))/sd(mang. df$height)
#
boxplot(samp. df$height, method="jitter", col="grayS0", xlab="height")

1) Getting data from a csv file

2) Performing standard deviation

3) Plotting a graph with the extracted data

d?

explanation:

solution:

this situation is called an ip conflict.

data from a server is sent in small bits called packets. in an ip conflict, some packets will end up in one computer while some other packets will end up in another computer.

so…overall none of the computers get the data as the original message or picture being sent by the server cannot be retrieved with only half the packets. so it will show up as an error.

thus the final answer is d.
