Answer:
The answer is "Approximately normal".
Step-by-step explanation:
sample size
Sample size
It is because the sampling distribution of the sample means is approximately normal.
Answer:
D: {0≤x≤20}
R: {0≤y≤200}
Step-by-step explanation:
Domain and range are the possible values of x and y, respectively. For continuous graphs in set notation, inequalities can be used to represent the x and y values. As seen on the graph, the lowest possible x value is 0 and the highest is 20. All of the other values in between are also included. So the inequality 0≤x≤20 expresses all of the values. Additionally, because the circles are closed, the limit values, 0 and 20, are included. Next, the range is found in the same way. The lowest y is 0 and the highest is 200, with the limits included. So, the range inequality is 0≤y≤200.
