Consider the sample of n = 20 scores. Notice that they are listed in order from 2.5 to 12.0, but that some of the scores are obscured by ***. The mean, M, of these scores is 8.0.
2.5 *** 4.6 5.1 *** 6.0 *** 6.5 6.6 8.5
8.7 9.6 *** 9.9 10.0 10.3 10.5 *** 11.6 12.0
Suppose you are asked for the sample standard deviation of these scores. Since you don’t have all of them, you cannot calculate it.
1. Which of the following is the best estimate of the sample standard deviation?
O 9.5
O 0.5
O 6.4
O 2.7

6 meters

what's the question?

step-by-step explanation:

there is no question.

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
