Ch2 Sec on 'Variance' last paragraph of Sec. |
This is in the ePub, which I'm reading on my iPad:
"This statistic is called the “sample variance,” and it is used to estimate the variance in a population using a sample. We will come back to this in Chapter ."
That's right. Chapter... what? No number or reference. In the PDF the quote is:
"This statistic is called the “sample variance,” and it is used to estimate the variance in a population using a sample. We will come back to this in Chapter 8."
Please fix this in the ePub..
Note from the Author or Editor:
I don't have the ePub version, so I can't confirm. Also, these links get auto-generated, so I can't fix it. |

From the referred URL (http://coolrunning.com/results/10/ma/Apr25_27thAn_set1.shtml) there is no division "F2029". The correct division would be "F2039".
Note from the Author or Editor:
The submitter is correct. I have made this change and checked in a modified XML file (revision 518192). |

Last paragraph |
The median of an exponential distribution is given as log(2)/lambda. Shouldn't that be ln(2)/lambda?
Note from the Author or Editor:
Yes, that would be clearer. Thanks! |
