You fly your rocket out to explore a star and on arriving you discover that it is actually a binary star. The two stars are separated by a distance of 0.3 AU and orbit one another with a period of 1 Month. a) What is the combined mass of the stars? b) Your spacecraft with a mass of $10^6$ kg is at a distance of 2 AU from the centre of mass of the stars and moving such that it has a kinetic energy of $1.2 \times 10^{15}$ J, is it in a circular orbit around the (centre of mass of the) two stars? c) Will your rocket remain bound in orbit or will it escape? Justify your answer. (No need for a full SUPER in this part, just need to answer the question with a supporting statement for justification).

Question 4 Let {X1, X2, ..., Xn} and {Y1, Y2, ..., Ym} be independent random samples from n(??, ??²) and ?(??, ??²) respectively. Furthermore, it is known that c?x² = d?y², with ?x², and ?y² are unknown parameters, and c, and d are known constants. (a) Construct a 100(1 - ?)% confidence interval for ?? - ??. (b) Suppose that c = 5, d = 6 and m = n, and the following independent random samples of X and Y are observed. X Y X Y X Y X Y 10.5 14.76 8 12.48 9.3 19.78 7.5 11.74 10.7 14.77 10.1 19.8 12.96 9.62 6.12 11.62 9.81 19.67 8.63 13.85 10.61 14.09 8.32 12.78 10.08 15.3 Assume that the maximum error ? = 0.5 for the 95% confidence interval needs to be achieved. Is the sample size large enough? If not, find the least sample size of m = n.
