In a combined Stat 100 and Stat 200 survey in Fall 2017, one question asked was "What month were you born in?". The data can be downloaded here and then loaded to R using the command
f17 <- read.csv("stat100_200_2017fall_survey04.csv")
A description of the column variables can be found on this webpage. Explore the data.
We want to test the following hypothesis:
H0: Students in Stat 100 and Stat 200 were born with equal probability in each month.
Expected proportion =
Largest proportion = (round to 3 decimal places) in January February March April May June July August September October November December
Smallest proportion = (round to 3 decimal places) in January February March April May June July August September October November December
p-value = (round to 3 decimal places)
Reject H0 at 5% significance level? No, do not reject H0: There is no/not enough evidence to suggest that students were not born with equal probability in each month. Yes, reject H0: There is a significant evidence to suggest that students were not born with equal probability in each month.
The next two parts of the problem will show up after you finish parts (a)-(c).
