10 Torch batteries of a particular brand are sold in packs of 3. A store receives a large delivery of packs. The manager selects a random sample of 60 packs and tests all of the batteries. The numbers of faulty batteries in the packs are summarised in the following table. Number faulty 0 1 2 3 Number of packs 28 28 4 0 (i) State one assumption about the batteries in a pack which you would need to make for a binomial distribution to be appropriate. (ii) Fit a binomial distribution to the data and carry out a goodness of fit test at the 10% significance level. (iii) 10 packs are selected at random from the delivery. Estimate the probability that at least two of these packs contain 3 faulty batteries.

The trade volume of a stock is the number of shares traded on a given day. The data in the first accompanying table, in millions (so that 6.16 represents 6,160,000 shares traded), represent the volume of a PepsiCo stock traded for a random sample of 38 trading days in 2018. A second random sample of 38 days in 2018 resulted in the data in the second accompanying table. Complete parts (a) through (d). EX Click here to view the data for sample 1.
