The distribution of the amount of money undergrads spend on books for a term is slightly right skewed with a mean of $400 & a standard deviation of $80. A) what is the probability that mean amount of money of 100 undergrads spent on books is less than $400? B) what is the probability that mean amount of money of 100 undergrads spent on books is between 400 and 500 dollars.  Please show work..I am trying to learn how to do this. I asked for extra questions,  not getting graded. Thank you
