Question

Several years ago, the state of California launched an aggressive advertisement campaign against smoking. We've interviewed students from 17 college campuses in California and recorded for each campus the percentage of students who claimed that they had encountered at least one anti-smoking advertisement on campus in the past month. Here are those percentages: 47.29, 31, 44, 60, 46, 36, 33, 39, 53, 39, 33, 25, 46, 36, 37,43 Using the tool provided, construct a box-and-whisker plot for the data 5 ? Percentage encountering more

Answer 1

SOlution:

use below R code to get boxplot

Rcode;

antismokad <- c(47,29,31,44,60,46,36,33,39,53,39,33,25,46,36,37,43)
antismokad
boxplot(antismokad,horizontal = TRUE)

Output:

35 40 45 50 55 60 25

To get fivenmber sumamry use fivenum function

R RStudio File Edit Code View Plots Session Build Debug Profile Iools Help IBE - Addins OR A Go to file/function O linreg R* x O Lab 2 Instructions Rev Spring 19.Rmd x O Untitled12* x O Untitled13* X O Untitled14*X O Untitled1 > -O O Notes.R* Console Terminal Jobs a AO Source on Save 1 antismokad <- c(47,29, 31,44,60,46,36,33,39,53,39,33,25,46,36,37,43) antismokad boxplot (antismokad, horizontal = TRUE) fivenum(antismokad) - Run * Source > fivenum(antismokad) [1] 25 33 39 46 60 2. 4.

FIVENUMBER SUMMARY IS

25 33 39 46 60

MIN=25

Q1=33

Q2=39

Q3=46

MAX=60

ANSWER:

35 40 45 50 55 60 25
