The z-statistic for Brett's data is found to be as given by: Option A: -5.30 (approx).
<h3>How to find the value of z-statistic for population mean?</h3>
Suppose we're specified that:
- The sample mean =
- The population mean =
- The population standard deviation =
- The sample size = n
Then the z-statistic for this data is found as:
For this case, we've got:
- The sample mean = = 295
- The population mean = = 310
- The population standard deviation = = 20
- The sample size = n = 50
Thus, we get:
Thus, the z-statistic for Brett's data is found to be as given by: Option A: -5.30 (approx).

The correct option is D
Step-by-step explanation:
The correct option is D.
They both have the same height, assuming that each coin has same volume, then how can coins in 1 stack have different volume than coins in another stack no matter how you stack them.
Like two cylinders with same base area and height have same volume. Like wise rectangle and parallelogram with same base and same perpendicular height having same area....
Try 12x3.14 for your answer hope it’s work
A. C= K-273.15
b. 300= C+273.15
300-273.15= C
26.85=C
