Answer:
The maximal margin of error associated with a 99% confidence interval for the true population mean backpack weight is 4.81 ounces
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 the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
So

The maximal margin of error associated with a 99% confidence interval for the true population mean backpack weight is 4.81 ounces
Answer:
-3/5
Step-by-step explanation:
-8/15 + (-1/15) = -8/15 - 1/15 = -9/15 = -3/5
- 1) 4 = 16 divided by n
- k + 5 = 11
- x - 2 = 7
- 7 times a = 42
- 6 = 1/3 times s
- r times 13 = 17
- b - 5 = 16
- No. It should be 24 = 8 times x
- 217 - x = 36
- p = 8180 - 6780
Step-by-step explanation: Cause it is
What number = x
x - 3.5 = 12.7
Isolate the x, add 3.5 from both sides
x - 3.5 (+3.5) = 12.7 (+3.5)
x = 12.7 (+3.5)
x = 16.2
16.2 is your answer
hope this helps
