Answer:
11.611 +/- 3.013
Explanation:
3 3.5 4 6 7 8 8.5 12.5 15
7 17 19 12 19 22 28 20 28
difference
4 13.5 15 6 12 14 19.5 7.5 13
mean = 11.611
the standard deviation ⇒ 7.611² + 1.889² + 3.389² + 5.611² + 0.389² + 2.389² - 7.889² + 4.111² + 1.389² = 57.927 + 3.568 + 11.485 + 31.483 + 0.151 + 5.707 + 62.236 + 16.9 + 1.929 = 191.386/9 = √21.265 = 4.611
standard deviation = 4.611 1.918
confidence interval = mean +/- [(standard deviation/√9) x 1.96]
11.611 + [(4.611/3) x 1.96] = 11.611 + 3.013
11.611 - [(4.611/3) x 1.96] = 11.611 - 3.013
We are given the different rates and charges and is asked in the problem the unknown tax rate she pays on meals if the total cost of the trip is equal ot $420.04. In this case, the equation goes:
80 x 3 + 80 x 0.1 x 3 + 80 x 0.09 x 3 + 109.3 x 1.15 + 109. 3 x z = 420.04
z = 0.08
