Explanation / Answer

a. you have a list of the current email addresses and telephone numbers of all the 378 students. Describe how you would derive an SRS of n=30 from this population .

I would use a stratified method of sampling that is choose every Nth of the telephone number book or email, for exmaple you can put the email and telephone number in a excel file and each telephone would have a number , so you will choose a phone every 10 numbers , that means 10 , 20 , 30 , 40 , etc

and you will have the sample of 30 in the number 300
