1. 5.25 - 5= 0.25

2. 5.5 - 4 = 1.5

Step-by-step explanation:

Last week:

2 + 3 + 3 + 3 + 4 + 4 + 7 + 7 + 7 + 7 + 8 + 8 = 63

63/12 = 5.25

This week:

2 + 2 + 2 + 3 + 3 + 4 + 4 + 6 + 8 + 8 + 9 + 9 = 60

60/12 = 5

Mean of strikes last week - Mean of strikes this week =

5.25 - 5 = 0.25

Last week:

2 3 3 3 4 4 7 7 7 7 8 8

4 + 7 = 11

11/ 2 = 5.5

This week:

2  2  2  3  3  4  4 6  8  8  9  9

4 + 4 = 8

8/2 = 4
