    I just wanted to say how helpful your videos are. My maths teacher makes everything confusing I always have to look online how to do anything as asking her again doesn't help as it is just as confusing, so I always stub,e across your videos and I get it first time. Thank you so much for your help. You definitely earned a subscriber

    Thank god. We were given one sheet that hardly even helped explain things to do over reading week with no help at all. It was so stupid, I’m glad I can use this to understand them now.

    Hey bro at 2.48 u said the answer is 13.617 and so round it to the nearest whole number which is 14. Don't you round it to 13 instead because you obviously can't have 13.6 of a person? You can't round it up to 14 either because again you can't have 13.6 of a person so you would need to round it to the lowest whole number?

      +Nehal Hussain If you always rounded down the sample size will always be lower than you wanted. For example if you wanted a sample size of 50 but always rounded down you would not get 50 people. For this reason round to the nearest whole number.

      +Maths Genie Yeah I understand now thanks man :D Im not joking... I have always been taught at school to always round down when people are involved. In certain situations I know that u have to but I was not aware of these sorts of questions. My whole life has been a lie lol. Thanks again
