<h3>
Answer: Choice B) 0.0015</h3>
==================================================
Explanation:
- mu = 65 = population mean
- sigma = 4 = population standard deviation
Let's convert x = 53 to its corresponding z score
z = (x-mu)/sigma
z = (53-65)/4
z = -12/4
z = -3
This indicates we're 3 standard deviations below the mean.
Recall that the Empirical Rule states that roughly 99.7% of the data items in a normal distribution are within 3 standard deviations of the mean. That leaves 100% - 99.7% = 0.3% outside this range. This small percentage is the combined percentage in both tails. Take half of this to find the amount in the left tail only.
(0.3%)/2 = 0.15%
This then converts to 0.0015 when we move the decimal point 2 spots to the left.

ur missing a x in the equation
Answer:
Answer: the 5-pound bag for $2.75 has the lowest price per pound.
Step-by-step explanation:
At the grocery store, she sees a 10-pound bag of potato for $5.90. It means that the cost per pound of potato is
5.9/10 = $0.59
She a 5-pound bag for $2.75. It means that the cost per pound of potato is
2.75/5 = $0.55
She sees a 11/2 pound bag for $0.99. It means that the cost per pound of potato is
5.5/0.99 = $5.56
Therefore, the 5-pound bag for $2.75 has the lowest price per pound.
