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. 46.5
Step-by-step explanation:
The formula to find the circumference of a circle is: 2πr
2(π x radius) or π times the diameter.
The radius is 7.4
7.4 x 2 = 14.8
14.8π ≈ 46.5
Answer: 100000
Step-by-step explanation:
That's 1 and then 5 zeros.
How?
10^5 = 10 • 10 • 10 •10 • 10 = 100000
