Latisha is buying frozen shrimp. she sees a 12-ounce pack for $14 and an 8-ounce pack for $12. what is the difference, to the nearest cent, of the unit price of one ounce of shrimp for each pack?

Solution:

we are given that

Latisha is buying frozen shrimp. She sees a 12-ounce pack for $14 and an 8-ounce pack for $12.

So the price of the unit ounce of Shrimp costing $14 for 12-ounce is $

So the price of the unit ounce of Shrimp costing $12 for 8-ounce is $

So the difference of price of unit Quantity $

The difference, to the nearest cent, of the unit price of one ounce of shrimp for each pack Cent

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.

step-by-step explanation:

irst, find the z score of a score of 80. this is given by the formula z = (x-u)/o, where x is the score, u is the mean, and o is the standard deviation. this gives

z = (80-78)/12 = 1/6 = .1667

now, find what percentile a z score of 1/6 correlates to in the normal distribution.

a z score of 1/6 = .1667 is equivalent to the 56.36th percentile of the distribution. so the probability a score is over this is 1-.5636 = .4364

the mean of a sample mean is equal to the original mean. however, the standard deviation of a sample mean is equal to the original standard deviation divided by the square root of n (sample size). so the new standard deviation is 12/sqrt(16) = 3.

the new z score is 80-78/3 = 2/3 = .667. this is equivalent to the 74.86th percentile. so the probability that the mean will be greater than this score is 1-.7486 = .2514.
