Answer:
1.125
Step-by-step explanation:
1) First you have to turn it into an improper fraction
8*1 = 8. Add the numerator--> 8+1 = 9.
2) The improper fraction is 9/8
3) Divide 9 by 8
**Write this using long division
8 goes into 9 one time, so we will write one as our first digit
Carry down the 1 and the 0, 8 goes into 10 1 times so write 1.
And this point we have 1.1 above
Carry down the 2 and the 0, 8 goes into 20 2 times so write 2
At this point we have 1.12
Carry down the 4 and the 0, 8 goes into 40 5 times with no remainders so write 5 and end the division process.
Now we have 1.125 as our decimal for 9/8 which is equivalent to 1 1/8.

Answer:
The 99% confidence interval for the difference between the true average load for the fiberglass beams and that for the carbon beams is (-11.937, -6.863).
Step-by-step explanation:
We have to calculate a 99% confidence interval for the difference between the true average load for the fiberglass beams and that for the carbon beams.
The sample 1 (Fiberglass), of size n1=26 has a mean of 33.4 and a standard deviation of 2.2.
The sample 2 (Carbon), of size n2=26 has a mean of 42.8 and a standard deviation of 4.3.
The difference between sample means is Md=-9.4.

The estimated standard error of the difference between means is computed using the formula:

The critical t-value for a 99% confidence interval is t=2.678.
The margin of error (MOE) can be calculated as:

Then, the lower and upper bounds of the confidence interval are:

The 99% confidence interval for the difference between the true average load for the fiberglass beams and that for the carbon beams is (-11.937, -6.863).
