Your answer is D :)
The % margin of error means that the real value is in the range between the mean less the margin error and the mean plus the margin error. This is [ mean - % of error, mean + % of error]. Then, in this case the error of +/- 2% means that the expected population proportion that wants flexible working hours is between 60% - 2% and 60% + 2%, which is between 58% and 62%.
9*2=18
18+9=27
There are 9 boys and twice as many girls so that means there is 18 girls and you have to find the total of boys and girls so you add 18 plus 9 to get a total of 27 students on the bus
this will equal 86 is the anwer to question u have asked
