The distribution of salaries of professional basketball players is skewed to the right. Which measure of central tendency would
True [87]

Answer:

Median

mean>median

Step-by-step explanation:

When the data is skewed to right the suitable average is median. Median is suitable because it is less effected by extreme values and thus locate the center of the distribution perfectly. Here the salaries of basket players are skewed to right and the best measure of central tendency to measure the center of distribution is median.

When the frequency distribution is rightly skewed then the relationship of mean and median is that mean is greater than median that is Mean>median.

Hence when the distribution is skewed to right the best choice to measure the center of distribution is median and when the data is skewed to right mean is greater than median.

\sqrt{210}

There is a theorem in Geometry stating that the square of the tangent segment (ST) is equal to the product of the external secant segment (TR) and the whole secant segment (TQ).

SQ x SQ = TR x TQ
SQ squared = 7 x 30
SQ squared = 210
SQ = \sqrt{210}
