1 answer:
Answer:
a) The sample size of two possible without replacement is 10
b) The population mean is 4.8 shutdown.
The population mean and the sample mean are the same.
Step-by-step explanation:
An image is attached showing the step by step solution.
a) This is a combination problem. We did 5 combination 2 to get 10 possible samples.
b) We generate the possible sample and find their means. Then find the mean of the sample mean which is also the same as the population mean.

Answer:
400
Step-by-step explanation:
first work out the radius of priya's circle with the equation a =
we know the diameter of a circle is 2 times the radius so the diameter of priya's circle is 2x
this means that if the diameter of dan's circle is 4 times bigger it must be
8x
to find the radius of dan's circle we divide the diameter by to 2 to give
4x
then use the a= equation again
which equals 400
