Hi, I'm struggling with how to solve this question. No other information was provided by teacher.

(a) (1 mark) Toss a coin 11 times and record the random variable X = the number of Heads in the table below, as well as the relative frequency [1/2 mark for each conect frequency) Number retative freq uencv X=1 X=Cl lb] (3 marks) Work out the sample mean. sam le variance and sample standard deviation sample mean sample variance sample standard deviation (cl [2 marks} from your research on the Internet, or using the lecture notes, some up with one other measure of volatility. Do you think the measure of voiatliitv you use is closer In concept to the variance or the sample standard deviation? Why? alternative volatility what volatility ls closest to and why id] {2 marks) Assuming the coin ls unbiased, work out the theoretical mean and standard deviation. mean standard deviation (e) (2 mark) Using your sampie in part (a) work out the average deviation of each value of X from the true mean. Write down two meanings of 'standard deviation' [1/2 mark each) average deviation meaning 1 meaning 2
