To find the test statistic or z-score given sample number (n), sample mean (x), standard deviation (σ), and population mean (μ), we can use

Given that n = 36, x = 24.6, μ = 20, and σ = 12,


From this, we see that the test statistic is 2.3.

Answer:
A $2000
Step-by-step explanation:
Let x be the least amount of money the club has to make to get $600 then...
30%x=600
We can convert 30% to a fraction. Any percentage is that number percent over hundred:

Simplify the fraction by dividing it by 10/10. Notice we can only do this since 10/10 is equivalent to 1, so in a sense we are dividing the fraction by 1:

Multiply 10 to both sides

Divide both sides by 3

The club would have to make at least $2000
