Suppose x has a distribution with µ = 18 and σ = 12. A button hyperlink to the SALT program that reads: Use SALT. (a) If a random sample of size n = 32 is drawn, find µx, σ x and P(18 ≤ x ≤ 20). (Round σx to two decimal places and the probability to four decimal places.)

The unpaid balance on a mastercard charge was $1,056.23. during the month, payments of $300 and $250 were made and charges of $425 and $274.16 were added. if the finance charge is 1.2% per month on the unpaid balance, find the new balance at the end of the month. $1,205.39 $1,218.06 $918.06 $1,768.06
