The Food and Drug Administration has determined that a substance called Melamine poses a health threat when it contaminates food. In fact, it poses a health threat even to dogs when it is in their food. Consequently, the FDA wants to monitor shipments of dog food imported into the country. From previous studies on dog food, the FDA knows that the population mean of Melamine in dog food is 8.0 grams in a 40 pound bag, with a population standard deviation of 1.5 grams. What is the likelihood that 36 40-pound bags of dog food randomly selected from an import shipment would have a mean of more than 8 grams of Melamine per bag Group of answer choices 0.50 None of the bags will have less than 8 grams All bags have at least 8 grams 0.05

answer: check all that apply, where the options?

step-by-step explanation:

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
