It is known that the amount of time needed to change the oil on a car is normally distributed with a standard deviation of 5 min
Dmitrij [34]

Answer:

(11.605 ; 22.195)

Step-by-step explanation:

11 10 16 15 18 12 25 20 18 24

Sample mean, xbar = Σx / n = 169 / 10 = 16.9

Standard deviation = 5.152 ( using calculator)

Confidence interval :

Xbar ± Margin of error

Margin of Error = Tcritical * s/√n

Df = n - 1 = 10 - 1 = 9

Tcritical at 99%, df =9 = 3.2498

Margin of Error = 3.2498 * 5.152/√10 = 5.2946

Lower boundary :

16.9 - 5.2946 = 11.6054

Upper boundary :

16.9 + 5.2946 = 22.1946

(11.605 ; 22.195)

Why is 6/8 greater than 5/8 but less than 7/8?
Phoenix [80]
Because if you draw a three pies and cut all of them into 8 pieces and shade 6 in one, 5 in the other, and 7 into the last one, you will see that there is a bigger piece shaded in the one with 6 shaded than the pie with 5 shaded. And less shaded than the one with 7 shaded. Hope I helped :)
