Answer:
1/36
Step-by-step explanation:
Given the sample space
S= [$1, $2, $5, $10, $20, $50] = 6
Hence the probability of choosing a
$5 bill is
Pr($5) = 1/6
Also the probability of choosing a $20 bill is
Pr($20) = 1/6
Therefore the probability of choosing a $5 bill and a $20 bill
Pr($5,$20) = 1/6*1/6= 1/36
Answer:

Now we can estimate the population variance with the sample variance given by:

And replacing we got:

And the estimator for the population deviation
is given by :

Step-by-step explanation:
For this case we have the following data given:
1.83,1.85,1.79,1.73,1.69,1.74,1.76,1.70
First we need to calculate the mean with the following formula:

And replacing we got:

Now we can estimate the population variance with the sample variance given by:

And replacing we got:

And the estimator for the population deviation
is given by :

Answer:
52.2%
Step-by-step explanation:
The total workforce is 11 + 12 = 23
Fraction of men =
= 
To change the fraction to a percentage multiply the fraction by 100%
percent of men =
× 100% = 52.2% ( to 1 dec. place )
It would be circular since it was cut from a cylindrical log.
