12 th percentile

48. 3; 4; 8; 8; 10; 11; 12; 13; 14; 15; 15; 16; 16; 17; 17; 18; 21; 22; 22; 24; 24; 25; 26; 26; 27; 27; 29; 29; 31; 32; 33; 33; 34; 34; 35; 37; 40; 44; 44; 47; Calculate the mean and the median

Mean=23.6 median=24

49. Mean is 30, the standard deviation is 6. Calculate the Coefficient of Variation

6/30*100=20

50. If the data were collected by asking the first 111 people who entered the store, then the type of sampling is:

convenience

51. Of the three measures, which tends to reflect skewing the most, the mean, the mode, or the median?

The mean tends to reflect skewing the most because it is affected the most by outliers.

52.Which is the greatest, the mean, the mode, or the median of the data set? 11; 11; 12; 12; 12; 12; 13; 15; 17; 22; 22; 22

Mean=15.1 mefian=12.5 mode=12 mean is the greatest

53. When the data are symmetrical, what is the typical relationship between the mean and median?

Mean=median are close or the same
