4

5

6

b) Choose the punish histogram (no proposal how i can delineation that so whatever)

c) whatever

d) furnish the moderation of the binomial dispensation

e)furnish the hostility of the binomial dispensation

f) furnish the rule disconnection of the binomial dispensation.

g) illustrate the results in composition of the existent society locality. what values of the vague unsteady would you ponder rare? illustrate your argueing.

on middle ____ out of 6 women would ponder thesmelves baseball fans,after a while a rule disconnection of ____ women. The values x = 6 and x = _____ would be rare accordingly their probabilities are (less/more/equal to) 0.05

5) Dedicated that x has a poisson dispensation after a while u=3, what is the propapbility that x =1?

P(1) =

6) Dedicated that x has a poisson dispensation after a while u=0.4, what is the propapbility that x =3?

P(3) =

7) Furnish the implied probabilities using the geometric dispensation or poisson dispensation. Then mention if the events are rare.

Assume the likelihood that you achieve shape a sale on any dedicated telephone flatter is 0.18. Furnish the likelihood that you (a) shape your original sale on the fifth flatter (b) shape your sale on the original, remedy or third flatter (c) do not shape a sale on the original three flatters

8) A newspaper furnishs that the moderation estimate of typographical errors per page is seven. Furnish the likelihood that (a) accurately six typo errors are endow on a page (b) at most six typo errors are endow on a page and (c) over than 6 typo errors are endow on a page.

9) A superior burst is a burst after a while wreath speeds of 111mph or important. During the conclusive eldership, the moderation estimate of superior bursts to impel a assured countries mainland per year was encircling 0.51. Furnish the likelihood taht in a dedicated year (a) accurately one superior burst achieve impel the mainland (b) at most one burst achieve impel the mainland, and (c) over than one superior burst achieve impel the mainland.
