<span>It can be assumed that the sample mean would would be approximately normal by the mean distribution theorem. The mean distribution theorem states that a large enough sample size will have a distribution and mean approximately the same as the population mean. A sample of 250, half the size of 500, is of sufficient size to assume the distribution mean will be approximately normal like the population mean.</span>

Answer:
Monica's monitor is not similar to Eugene's monitor.
Step-by-step explanation:
It is given that the display resolution of Monica's monitor is 240 pixels by 160 pixels and the display resolution of Eugene's monitor is 320 pixels by 200 pixels.
Ratio of the lengths of Monica's monitor and Eugene's monitor = 240:320
= 3:4
Ratio of the heights of Monica's monitor and Eugene's monitor = 160:200
= 4:5
3:4 ≠ 4:5
Hence, Monica's monitor is not similar to Eugene's monitor.
