Answer:
p(picking red)= 4/12 (4 over 12) which can get simplified to 1/3 (1 over 3)
Negative 12 is already a fraction on its own. If you say -.12, it will be -3/25
Based on the population mean, the mean of the distribution sample means would be 204.6. The standard deviation would be 0.22.
<h3>What are the mean and standard deviation of the distribution?</h3>
The mean of the distribution sample means is the same as the population means which is 204.6.
The standard deviation can be found as:
σₓ = σ / √n
= 3.1 / √197
= 0.22
