q1a_1-generate_table

## Fill in the probabilities column wise.
observed_frequencies <- matrix(rmultinom(1, size = 125, prob = c(0.15, 0.45, 0.10, 0.30)), nrow = 2)
# the matrix function creates a 2 by 2 table by specifying nrow = 2
observed_frequencies

Result

     [,1] [,2]
[1,]   24   10
[2,]   50   41

q1a_2-chi_square_test

## Chose the right logical indicator
observed_frequencies
chisq.test(observed_frequencies, correct = FALSE)

Result

     [,1] [,2]
[1,]   28   13
[2,]   43   41
