Let the random variable x have a discrete uniform distribution on the integers 8 ≤ x ≤ 11. determine the mean, μ, and variance, σ2, of x. round your answers to two decimal places (e. g. 98.76).

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle
