Using the textbook data set nlschools.csv, perform a hypothesis test to determine whether the proportion of students with

verbal IQ scores greater than 11 is different for students from families of social-economic status at most 25 and students from

families of social-economic status greater than 25. Perform the test at the alpha = 0:05 significance level.

Tips:

A description of the data is available in the le nlschools readme.txt

Note that the data provided is for 200 students, not the entire 2287 from the study.

After importing the data, the command subset(nlschools, SocEconStatus <= 25)$VerbIQ could be used to access

just the Language values for studentsfrom families of social-economic status at most 25.

If x is a list of values, we could count the number of values in x using the command length(x)

If x is a list of values, we could count the number of values in x that are greater than 25 using the command

sum(x > 25)
