Answer:
7
Step-by-step explanation:
It is 7:
31 - 7 = 24
15 - 7 = 8
8/24 = 1/3 = 33%
It is not 12:
31 - 12 = 19
15 - 12 = 3
3/19 = 15%
It is not 6:
31 - 6 = 25
15 - 6 = 9
9/25 = 36%
It is not 9:
31 - 9 = 22
15 - 9 = 7
7/22 = 31%
It is not 11:
31 - 11 = 20
15 - 11 = 4
4/20 = 20%
<u>I subtracted the option from 31 (the new total of marbles) and from 15 (the new total of blue marbles). Then, I divided the new total by the new total of the blue marbles. I converted the decimal into a percentage. If the percentage was not 33%, then it was not the answer.</u>
Answer:
Critical value z = 2.574
Confidence interval = ( $71.596 to $93.264)
Step-by-step explanation:
Mean x = $82.43
Standard deviation r = $13.96
Number of sample n = 11
Confidence interval of 99%
Critical value = z = t(a/2)
a = 1 - 0.99 = 0.01
a/2 = 0.01/2 = 0.005
z= t(0.005) = 2.57
z = 2.574
Confidence interval = x+/-(z×r/√n)
= 82.43 +/- (2.574 × 13.96/√11)
= 82.43 +/-10.834
Confidence interval = ( 71.596 to 93.264)
