A February 2020 survey collected data on Brazil’s government transparency score, where 0 represents the lowest possible ranking and 10 the highest. A small random sample of 12 international watchdog sources provided the following rankings: 4.5 9.2 3.1 6.0 5.8 8.4 2.7 7.5 4.3 6.1 3.8 5.9 An analysis of the data yielded a sample mean of x̄ = 5.45 and a sample standard deviation of s = 1.85. A Brazilian government spokesperson claims that the true average ranking of Brazil in government transparency is at least 8. a) State the null and alternative hypotheses. b) Conduct a hypothesis test using significance level α = 0.01. c) Construct a 98% confidence interval for the population mean transparency ranking. d) Interpret your results in context. Do the data support the government’s claim?

Let f(x)=a(x)^2 + bx + c where a>0. We intend to find local minimum of this function using gradient descent with hyper parameter alpha. If x (subscript n) represents value of the variable x after nth step, is it possible to write x (subscript n+k) = x (subscript n) * (P)^k + Q where P and Q are constants? If so, find P and Q. Otherwise explain the reason if it is not possible to write x (subscript n+k) in the suggested form. Does there exist a set of values of alpha for which the algorithm is guaranteed to converge.? If so, find these values of alpha. Give a mathematical justification of your answer.
