Answer:
Step-by-step explanation:
For this case we are interested on the region shaded on the figure attached.
And we can find the volume with the method of rings.
The area on this case is given by:
And the volume is given by the following formula:
For our case our limits are x=0 and x=2 so we have this:
And if we solve the integral we got this:
And after evaluate we got this:
Answer:
a) <em> standard error of the mean =10.06</em>
<em>b) The margin of error = 17.3982</em>
<em>c) 95% of confidence intervals are </em>
<em></em><em></em>
<em>d) Lower limit of 95% of confidence interval = 89.6018</em>
<em>upper limit of 95% of confidence interval = 124.3982</em>
<em>The Population mean is lies between in these intervals</em>
<u>Step-by-step explanation:</u>
<u><em>Step(i)</em></u><u>:-</u>
Given sample size 'n' = 20
Given sample mean was found to be 107 bpm with a standard deviation of 45 bpm.
<em>Sample mean </em><em></em>
<em>Sample standard deviation (S) = 45 bpm</em>
<em>a) standard error of the mean is determined by</em>
<em> </em><em></em>
<em> S.E = 10.06</em>
<em>b) The margin of error is determined by</em>
<em></em><em></em>
<em>The degrees of freedom ν </em><em></em>

<em></em><em></em>
<em>d) </em>
<em>Lower limit of 95% of confidence interval = 89.6018</em>
<em>upper limit of 95% of confidence interval = 124.3982</em>
<em>The Population mean is lies between in these intervals</em>
