Answer:
Step-by-step explanation:
The range of a data set is the difference between the biggest value and the smallest value.
We are given this data set:
- 8, 4, 6, 6, 8, 2, 6, 5
If we order it from smallest to largest:
- 2, 4, 5, 6, 6, 6, 8, 8
We see that the smallest value is 2 and the largest is 8. Now we can find the range.
- range= largest value - smallest value
- range= 8-2
- range= 6
The range for the data set is <u>6.</u>

Answer:
(12.1409, 14.0591
Step-by-step explanation:
Given that Tensile strength tests were performed on two different grades of aluminum spars used in manufacturing the wing of a commercial transport aircraft. From past experience with the spar manufacturing process and the testing procedure, the standard deviations of tensile strengths are assumed to be known.
Group Group One Group Two
Mean 87.600 74.500
SD 1.000 1.500
SEM 0.316 0.433
N 10 12
The mean of Group One minus Group Two equals 13.100
standard error of difference = 0.556
90% confidence interval of this difference:
t = 23.5520
df = 20
