*I say in this video that you should be rounding the sample size up
to the nearest whole integer since that is what many others recommend and
since that yields a more conservative estimate of sample size. However,
this text actually wants you to round normally, so you should round to
the nearest whole number to have answers matching the answers
sanctioned as correct in this text. |
