Acompany maintains three offices in a region, each staffed by two employees. information concerning yearly salaries (1000’s of dollars) is as follows: office 112233 employee 123456 salary 29.7 33.6 30.2 33.6 25.8 29.7 a. suppose two of these employees are randomly selected from among the six (without replacement). determine the sampling distribution of the sample mean salary x. b. suppose one of the three offices is randomly selected. let x1 and x2 denote the salaries of the two employees. determine the sampling distribution of x. c. how does e(x) from parts (a) and (b) compare to the population mean salary m?

1. sometimes

2.   never

3   .08c = 7.50+.05c   250 pages

step-by-step explanation:

1.   sometimes

the theoretical probability of rolling a 1 is 1/6.   perhaps you got really lucky and never rolled a 1   in those 60 times.   your experimental probability is 0.   or perhaps you rolled a 1   20 times.   your experimental probability is 20/60 is 1/3.     it really just depends on how you rolled in that experiment.

2.   never

the probability of the event occurring is 1.   that is being 100 % sure it will happen.   that is the maximum amount of confidence we have.

3.   no customer card cost:   .08 times number of pages

customer card cost:   7.50 + .05 times number of pages

we want to find when it costs the same amount, so we will set these equal

let c = number of pages

.08c = 7.50+.05c

subtract .05c from each side

.08c-.05c = 7.5+.05c-.05c

.03c=7.5

divide each side by .03

.03c/.03 = 7.5/03

c =250  

the cost is the same at 250 pages

the answer is 40.

proof:

first 15 divide by 2 = 7.5

100 divided by 7.5 is 13.

15 / 2 = 7.5

100 / 7.5 = 13.
