Answer: sorry dont know
Step-by-step explanation:
The answers are 2460, 37,000, 3670 and 5000
Step-by-step explanation:
- Step 1: Find the answers for each by multiplying.
24.6 × 100 = 2460 (moved one decimal point)
37 × 1000 = 37,000
0.367 × 10000 = 3670 (moved three decimal points)
0.005 × 1000,000 = 5000 (moved three decimal points)
192 is the answer definately
Answer:
Step-by-step explanation:
Notation
represent the sample mean
population mean (variable of interest)
s represent the sample standard deviation
n represent the sample size
Solution to the problem
The confidence interval for the mean is given by the following formula:
(1)
For this case the 9% confidence interval is given by:
We can calculate the mean with the following:
And we can find the margin of error with:
The margin of error for this case is given by:
And we can solve for the standard error:
The critical value for 95% confidence using the normal standard distribution is approximately 1.96 and replacing we got:
Now for the 98% confidence interval the significance is and the critical value would be 2.326 and then the confidence interval would be:
Answer:
the difference between 5/8 and -1/3
is that if you divide 5/8 = 0.625
and -1/3= -0.333333333
