The average X bar would be 9.78

Take all players

Then divide by the total number of players 14

147/14 = 9.79 with rounding to the second placement (100ths)

Step-by-step explanation:

4400

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
