I need a step by step example of how to get the answer if you don't mind.

Answer:

D

Step-by-step explanation:

This equation may look hard, but all of the steps are in the question, so all we need to do now is plug in the numbers!

The question asks us to round all numbers to the nearest whole number before plugging them in, so we'll round 11.3 down to 11.

Now, we just need to plug in 11 to the equation to ger A=11²pi

11 squared is 121, so now we just need to multiply 121 by pi.

Pi is a long number, but again, the equation asks us to round to the nearest whole number, so since pi is 3.143, we can round that to three.

Now all we need to do is multiply 121 by 3 to get 363!

I hope this helps.

A large bakery makes cakes in two shifts: shift A and shift B. Suppose that, on average, cakes from shift A weigh
7.4 kg with a standard deviation of 0.2 kg. For shift B, the mean and standard deviation are 7.0 kg and 0.1 kg,
respectively.
Every day, the bakery takes an SRS of 25 cakes from each shift. They calculate the mean weight for each sample,
then look at the difference (A - B) between the sample means.
What are the mean and standard deviation (in kilograms) of the sampling distribution of CA - TB?
