Answer

mean=43.31,meduan=41 and mode is 41

Work Step by Step

You have the values 47,41,22,17,55,34,71,46,39,41,38,60,52. To find the mean, add all the values together and divide by 13: $\frac{47+41+22+17+55+34+71+46+39+41+38+60+52}{13}$=43.31. To find the median arrange the numbers from least to greatest (17,22,34,38,39,41,41,46,47,52,55,60,71) The middle value is 41. The mode is the number which occurs the most and since 41 occurs the most in this data set, it is the mode.
