Step-by-step explanation:
Answer:
Sample Variance = 6.008
Sample standard deviation = 2.451
Step-by-step explanation:
We are given the following in the question:
10.6, 12.6, 14.8, 18.2, 12.0, 14.8, 12.2, 15.6
Formula:
where
are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 42.06

Standard Deviation =

About 15 type of dinner
C + S = 6
14.8C + 17 S = $91
=> 14.8C + 17 ( 6 - C ) = 91
Can you solve from here?
Hope I can help you:)
