Sunshine High School claims that 72% of its students complete their homework on a daily basis. Ms. Carter surveyed 80 students and found that only 60% complete their daily homework. What does the test statistic calculation look like in this situation for an appropriate hypothesis test? z equals 0.60 minus 0.72 all over the square root of the quantity 0.72 times 0.28 over 80 z equals 0.60 minus 0.72 all over the square root of the quantity 0.60 times 0.40 over 80 z equals 0.60 minus 0.72 all over the square root of the quantity 0.60 times 0.72 over 80 z equals 0.72 minus 0.60 all over the square root of the quantity 0.60 times 0.40 over 80 z equals 0.72 minus 0.60 all over the square root of the quantity 0.72 times 0.28 over 80
