Question

According to a survey,

61%

of murders committed last year were cleared by arrest or exceptional means. Fifty murders committed last year are randomly selected, and the number cleared by arrest or exceptional means is recorded.

(a) Find the probability that exactly

of the murders were cleared.

(b) Find the probability that between

and

of the murders, inclusive, were cleared.

of the murders were cleared? Why or why not?

(a) The probability that exactly

of the murders were cleared is

(Round to four decimal places as needed.)

(b) The probability that between

and

of the murders, inclusive, were cleared is

(Round to four decimal places as needed.)

of the murders were cleared? Why or why not?

No, it would not be unusual because

is less than

μ−2σ.

Yes, it would be unusual because

is between

μ−2σ

and

μ+2σ.

Yes, it would be unusual because

is less than

μ−2σ.

No, it would not be unusual because

is between

μ−2σ

and

μ+2σ.
