176 rounds up to 180
17 rounds up to 20
The fact we're rounding up both times means we'll have an overestimate
estimate = 180*20 = 3600
actual result = 176*17 = 2992
Answer:
standard deviation is 2.886 [expected points]
Step-by-step explanation:
Let x is number of points scored so that given target uniformly dstributed between 0 and 10
clearly X uniform(0,10)
mean is defined as
we know that variance is given as
= 8.333
therefore standard deviation is
standard deviation is 2.886 [expected points]
