I think it’s a because it’s talking about consumer electronics
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
