Acertain manufactured product is supposed to contain 23.2% potassium by weight. a sample of 10 specimens of this product had an average percentage of 23.6 with a standard deviation of 0.3. if the mean percentage is found to differ from 23.2, the manufacturing process will be recalibrated. do the following.
(a) state the appropriate null and alternative hypotheses that you should use in this situation.
(b) compute the test statistic.
(c) compute the p-value
(d) state the conclusion of the test in the context of this setting.

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )

i think the amount would be $140.62
