upper and lower bound pls An article in Radio Engineering and ElectronicPhysics (1984, Vol. 29, No. 3, pp. 63–66) investigated thebehavior of a stochastic generator in the presence of externalnoise. The number of periods was measured in a sample of 100trains for each of two different levels of noise voltage, 100 and150 mV. For 100 mV, the mean number of periods in a train= 2.6. For 150 mV, the mean was 6.9 withwas 7.9 with ss = 2.4.Find a 99% confidence interval on the difference in meannumber of periods µ1 - H2. Assume that both populationvariances are equal.What is the upper bound? Three decimal places

Question 1 A biscuit factory has three machines used to pack biscuits into large boxes that are then sent out to supermarkets. The machines are labelled A, B, and C, and every day each machine packs many boxes of biscuits. The machines work at different speeds: from all the boxes produced on a given day 40% were packed by A, another 40% by B, and the remaining 20% by machine C. Some biscuits break during the packing process, which is a problem. Machine A does this quite a lot: for any box packed by A there is a probability 0.1 that it contains some broken biscuits. Machine B is better, with a probability 0.03 that a box from that machine will contain some broken biscuits. Machine C is best of all, with a probability of just 0.01 that a box it packs will have some broken biscuits. All of these probabilities are independent for every box. Before the boxes are sent out from the factory a few are picked out at random and checked to see whether they contain any broken biscuits. 1.1 What is…
