The standard error of the mean is given by:
![\frac{\sigma}{\sqrt[]{n}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%5B%5D%7Bn%7D%7D)
where sigma is the standard deviation and n is the sample size. In this case the sample size is 10 and the standard deviation is 0.657, then the standard error is:
![\frac{0.657}{\sqrt[]{10}}=0.208](https://tex.z-dn.net/?f=%5Cfrac%7B0.657%7D%7B%5Csqrt%5B%5D%7B10%7D%7D%3D0.208)
Therefore the standard error is $0.208.

Answer: (21,12)
Step-by-step explanation:
Given:
Grocery store: 8 ounces of blueberries = $2.80
Farmer's market : 14 ounces of blueberries = $4.20
1 pound = 16 ounces.
Unit rate: per ounce
Grocery store: $2.80 ÷ 8 oz = $0.35 per ounce
Farmer's market: $4.20 ÷ 14 oz = $0.30 per ounce
Unit rate per pound
Grocery store: $0.35 per ounce * 16 ounces = $5.60 per pound
Farmer's market: $0.30 per ounce * 16 ounces = $4.80 per pound
