Here the question notes, normal body temperatures vary by the time of day, and a series of readings were taken of the body temperature of a subject.
00:09
The mean reading was found to be 36 .5 degrees celsius with a standard deviation of 0 .3 degrees celsius.
00:15
And if we think about that, when fahrenheit is 1 .8 degrees celsius plus 32.
00:20
When converted to fahrenheit, the mean and standard deviation are.
00:26
So this is kind of a question about how, like, manipulative.
00:30
And conversion of the data will affect standard deviation in the mean.
00:35
So the effect of multiplying all the numbers of a data set is that all the summary statistics will change by that same multiplication.
00:42
Adding to a data set will affect all summary statistics except measures of spread, which would be standard deviation.
00:50
So the adding will not affect the standard deviation, but the multiplication will.
00:54
So let's just see what the effect that has.
00:56
If we recall, our mean is 36 .5 degrees celsius.
01:03
And we'll say this is mean.
01:07
And our standard deviation was 0 .3 degrees celsius.
01:14
So we have our formula.
01:17
Fahrenheit equals degrees celsius times 1 .8 plus a flat 32.
01:27
Okay.
01:29
That's the formula for fahrenheit...
