EXPLANATION
Given:
Desired Outcome:
Probability that it will last 10 years
z-score for the sample:
p-value
For the z-score of 1.9376, the p-value is 0.9738 or 97.38%
Hence, the probability that it will last longer than 10 years if you randonly purchase one item is 97.38%
If you are trying to find the unit rate, or amount per pound, you would divide 299 by 14, and add the decimal point where it was. So, 299/14=21.35. After you do the division, move the decimal point 2 places to the left. So, 21.35 with the decimal point 2 places to the left=21 cents. So the unit rate of 2.99 for 14 pounds is 21 cents per pound.
That's your answer
