TX TX 2 MI TX Rv TX Rv TX e'en UC FM UGC3

Step-by-step explanation:

23

Answer 2

Answer:

Range = 43

Range - The difference between highest and the lowest observation in the given data.

Highest observation = 58

Lowest observation = 15

= 58-15

= 43

Mean = 35

Mean - Sum of all observation/ Number of observation

= 37 + 15 + 40 + 30 + 58 + 25 + 40 / 7

= 245 / 7

= 35

Median = 37

Median - First we have to arrange in ascending order, then we have to choose the middle number.

= 15, 25, 30, 37, 40, 40, 58

= 37

Mode = 40

Mode - The observation which of occurs maximum number of times in the given data.

= 40 (It occurred 2 times)
