Question

1. Section 1.6, Exercise 10 Setting 1 for Heads and O for Tails, the outcome X of flipping a coin can be thought of as resulting from a simple random selection of one number from (0, 1). (b) The posible samples of size two, taken with replacement from the population (0, 1), are (e) Consider the statistical population consisting of the four sample variances obtained in (d) Compare σ륫 and E(Y). If the sample variance in part (b) was computed according to a (a) Compute the variance σ of X. (0,0), (0,1), , samples. Compute the sample variance for each of the possible four part (b), and let Y denote the random variable resulting from a simple random seloction of one number fron this statistical population. Compute E(Y). formula that divides by n instead of n-1, how wonld σ and E(Y) ompare? 2. Section 2.2, Exercise1 Give the sample space for each of the following experiments (a) A die is rolled twice and the outcomes are recorded (b) A die is rolled twice and the sum of the outcomes is recordked (e) From a shipment of 500 iPods, 6 of which have a click wheel problem, a simple random sumple of 30 iPocds is taken and the mumber found to have the click wheel problen is recorded (d) Puses are inspected until the first defective fuse is found. The mumber of fuses inspected is recorded SAMSUNG 8 5 8 9 0 lOP
