Answer:
The 99 percent confidence interval for the true mean number of full-time employees at office furniture dealers is (12.288, 32.622).
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 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the mean subtracted by M. So it is 22.455 - 10.167 = 12.288
The upper end of the interval is the mean added to M. So it is 22.455 + 10.167 = 32.622
The 99 percent confidence interval for the true mean number of full-time employees at office furniture dealers is (12.288, 32.622).
Answer:
B
Step-by-step explanation:
Substitute the values in for x and y and you will see B is correct.
Davis's claim was incorrect because a rectangle sometimes only have 2 congruent sides. Drawing a rectangle, the length/width would be longer than their length/width. Unless it is a square, it counts as correct as a square can be counted as a rectangle and a rectangle can not be counted as a square but anyways, congruent means equal sides. The rectangle, mostly drawn, only has two long sizes and two short sides, both opposides are equal. Hence, the claim Davis said is incorrect.
Answer:
B. -11
Step-by-step explanation:
ascending order means least to greatest.
-10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7,...
3, -1, 
, 13, -11
-11 is the least number because it is the greatest negative number
