Suppose you want to estimate the difference between two population means correct to within 1.9 with a 99? % confidence interval. if prior information suggests that the population variances are approximately equal to sigma subscript 1 superscript 2equalssigma subscript 2 superscript 2equals11 and you want to select independent random samples of equal size from the? populations, how large should the sample? sizes, n 1 and n 2? , ? be?

the sample sizes should be n 1 equals n

Amodified roulette wheel has 36 slots. one slot is 0, another is 00, and the others are numbered 1 through 34, respectively. you are placing a bet that the outcome is an odd number. (in roulette, 0 and 00 are neither odd nor even.) a. what is your probability of winning? the probability of winning is startfraction 17 over 36 endfraction . (type an integer or a simplified fraction.) b. what are the actual odds against winning? the actual odds against winning are nothing: nothing. c. when you bet that the outcome is an odd number, the payoff odds are 1: 1. how much profit do you make if you bet $10 and win? if you win, the payoff is $ nothing. d. how much profit should you make on the $10 bet if you could somehow convince the casino to change its payoff odds so that they are the same as the actual odds against winning? $ nothing (round to the nearest cent as needed.)
