Answer:
34
Step-by-step explanation:
Let the no. be x,
2x-3=3x+31
3x-2x= -3-31
x= -34
Since we know that a - 2 will equal 8, it is safe to assume that 8 + 2 = 10. Therefore a=10.
The sample mean is the sum of the sample values divided by the number of them:
(7 +7 +10 +6 +9 +6 +8 +7.5 +8.5 +8)/10 = 77/10 = 7.7
The sample mean is 7.7.
