- 1 (a) Discuss the two expressions -x;- )² and E(x;- )², both of which are used (n-1) i=1 to measure the spread of a set of observations x1, x2, . .., X. (b) A random sample of n observations is taken from a distribution; the sum of the observations is t, and the sum of the squares of the observations is 12. Explain how to estimate the mean and the variance of the distribution from which the random sample was taken. (c) Given the random sample described in part (b), write down expressions (based on 11 and t2) for estimates of the mean and variance of the mean of a further, independent, random sample of size m , from the original distribution. (d) Given that n = 25, 1, = 400 and t2 = 8800, construct a 99% confidence interval for the mean of the distribution, and use it to test whether or not this mean could be 20.Please solve within 20 minutesIf P(A) = 0.5, P(B) = 0.4, and P(A^ B) = 0.25, then P(AUB) = 0.35 0.15 0.65 0.9
- A cereal manufacture claims that the gross weight (including packaging) of a box of cereal weight is uniformly distributed between 11.5 oz and 14 oz.

Find the variance Var[A].(b) Ten people play the arcade machine; each one keeps playing until they win, and thenit’s the next person’s turn. Let B be the number of times they play in total. Find thevariance Var[B].(c) Ten years later, you come back to the arcade machine, and it’s exactly the same, exceptthat due to inflation, the machine costs $10 to play.Let C be the the total cost of playing until you win. Find the variance Var[C].Will you help me with this one again?

(a) U = number of times a surfer has to paddle in front of a wave before catching one (b) X = length of a randomly selected angelfishplease helpIn this unit, three important characteristics of a binomial experiment are summarized: fixed number of trials. two possible outcomes; and n independent trials repeated using the same conditions. Based on the above mentioned characteristics, Think of a binomial experiment example from your own area of interest. Describe how the experiment selected meets all the characteristics of a binomial experiment.
