Q1) Recent survey illustrates that 680 out of 1050 respondents agree with principle of University top-up fees. Use this data to deduce 95% and 99% confidence intervals for proportion of the general population in favour of such fees. Compute a p-value for the null hypothesis H₀: p = 2/3 against the alternative H1 : p ≠ 2/3 . Is it sensible to argue that two-thirds of the general population are in favour of such fees?
