An unconfined compression test was performed to determine the average strength of concrete cylinders (in psi). It is believed that the strength is approximately normally distributed with a standard deviation of 256 psi. A sample of 70 concrete cylinders was taken, and it was found that the average strength was 3000 psi. Find a 91% confidence interval for the true average strength of the concrete.
Be sure to:
• State the value for α.
• State whether you should use z or t and find the appropriate value. Round z-values to 2 decimals. Round t-values to 3 decimals.
• Find the confidence interval (to 2 decimals). State the parameter your confidence interval is for.
• Write a verbal interpretation of your confidence interval.
Answer:
Explained below.
Step-by-step explanation:
(1)
The confidence level is, 91%.
Compute the value of α as follows:
[tex]\text{Confidence level}\% =(100-\alpha \%)\\\\91% = 100-\alpha \%\\\\\alpha \%=100-91\%\\\\\alpha \%=9\%\\\\\alpha =0.09[/tex]
(2)
As the population standard deviation is provided, i.e. σ = 256 psi, the z value would be appropriate.
The z value for α = 0.09 is,
z = 1.69
(3)
Compute the 91% confidence interval as follows:
[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]
[tex]=3000\pm 1.69\cdot\frac{256}{\sqrt{70}}\\\\=3000\pm 51.71\\\\=(2942.29, 3057.71)[/tex]
(4)
The 91% confidence interval for population mean implies that there is a 0.91 probability that the true value of the mean is included in the interval, (2942.29, 3057.71) psi.

The winner of a jump rope contest jumped 4 times as long as the person who finished in fifth place. The fifth place finisher jump rope for 120 seconds. Which equation shows the total number of seconds the winner jumped rope?
Answer:
x= 4*120
Step-by-step explanation:
The 5th place person jumped for 120 seconds
The 1st place jumped 4 times as long
So 120 times 4 = 480 seconds or 8 minutes

Using the paths shown, the distance from Brookfield to Seaside is 20.4 kilometers.
How far is it from Brookfield to Yardley?
Answer:
7.2 km
Step-by-step explanation:
Distance between Brookfield to Seaside = 20.4 km
Distance between Yardley and Seaside = 13.2 km
Let distance between Brookfield to Yardley be x.
Thus:
x + 13.2 km = 20.4 km
Subtract 13.2 from each side
x = 20.4 - 13.2
x = 7.2
Distance from Brookfield to Yardley is 7.2 km

Which table of values could be generated by the equation -10x+5y=15
9514 1404 393
Answer:
see below
Step-by-step explanation:
I find it convenient to factor 5 from the equation and re-order the left side:
y -2x = 3
This makes it relatively easy to see that the values in the left-most table will satisfy this equation.
__
If we look at the table values for x=2, where all the tables differ, we can easily find the one that works:
1. 7 -2(2) = 3 . . . . this value works in the equation
2. 0.5 -2(2) = -3.5 . . . . no
3. -1 -2(2) = -5 . . . . no
4. 2.5 -2(2) = -1.5 . . . . no

They suggest that the audience has listened to and understood all of Truth’s reasons.
Step-by-step explanation:
Obliged to you for hearing me, and now old Sojourner ain’t got nothing more to say.
