4 0

The answer is the chi square distribution. In Statistics and probability theory, the chi distribution is a continuous probability distribution. The chi-square distribution is a distinct case of the gamma distribution and is one of the most extensively used probability distributions in inferential statistics for instance, in construction of confidence intervals or in hypothesis testing.

Step-by-step explanation:

Why? Becuase take 45% and convert it into decimal form

45%--->0.45

Then take 920

920 × 0.45

414

So we know that 414 is 45% of 920!

And That is your answer!

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]
