Answer:
The UCL of the 95% confidence interval for population mean is 10.16 minutes
Step-by-step explanation:
We have that to find our level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of .
That is z with a pvalue of , so Z = 1.96.
Now, find the margin of error M as such
In which is the standard deviation of the population and n is the size of the sample.
The upper end of the interval is the sample mean added to M. So it is 9.3 + 0.86 = 10.16 minutes.
The UCL of the 95% confidence interval for population mean is 10.16 minutes
Answer:
x - 8 ≤ 4
+8 +8 Add eight to both sides of the equation.
X≤12
2x + 3 > 9
-3 -3 Subtract three from both sides
2x>6 Divide both sides by 2
x>3
Hope this helps!
Have an amazing day/night!
<span>The identity element when applied does not change the other elements hence in multiplication 1x7=7 and 1x5=5 the elements 5 and 7 do not change for addition its 0 such as 0+10=10.

The remainder (which is what Blake says is the remainder), can never be more than the number you are dividing by (the dividend), which in this problem is three.
Divide 136 by 3 and you will prove that answer is incorrect.
A=33/2 simplified is 16 1/2, 16.5
