**How would I write out Part C for this problem ? What would the code look like because I'm unsure if I should use a new data set or not. I also don't know how to make a normal table of cumulative probabilities. I've done most of the problem already but I'm just stuck on this last part. Any help please on how the code would look and what the functions do exactly ? Thank you !**
