A Distributions with few scores are moreless likely to have

A.) Distributions with few scores are more/less likely to have a mode than distributions with many scores.

Solution

A. Distributions with few scores are less likely to have a mode than distributions with many scores because there are less data points so there is a less chance of having multiple points of the same value. If there are many points, it is likely that some of them will repeat.

B. X-bar and mu are both measures of a mean. X-bar is the calculated sample mean, while mu is the population mean. Sometimes mu is not always known so it is approximately by x-bar.
