A person aiming at a target receives 10 points if their shot is within 1 inch of the target, 5 points if it is between 1 and 3 i
Gelneren [198K]

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 E(x) = \frac{a+b}{2}

                                       \frac{0+10}{2} = 5

we know that variance is given as \frac{(b-a)^2}{12}

V(x) = \frac{(b-a)^2}{12}

       \frac{(10-0)^2}{12}

       = 8.333

therefore standard deviation is \sqrt{V(x)} = \sqrt{8.333}

standard deviation is 2.886 [expected points]
