Answer:
And we are confident that the true mean for this case is given by
Step-by-step explanation:
Data given
represent the sample mean for the WBC
population mean
s=3.9265 represent the sample standard deviation
n=187 represent the sample size
Confidence interval
The confidence interval for the true mean is given by:
[tex]\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}[/tex] (1)
The degrees of freedom, are given by:
The Confidence level is 0.90 or 90%, the significance is and , the critical value for this case would be
Replacng into the formula we got:
And we are confident that the true mean for this case is given by
Answer:
D
Step-by-step explanation:
When you flip a point around the y axis the x value is inverted since the point is moved to the opposite side across the y axis.
Associative property is the answer
* remember to do whats in parenthesis first
(90 x 7) = 630 and (7 x 2) = 14
add them both up
answer: 644
