Question

probability mass function? I bought 12 eggs which weight 54,55,57,59,59,61,63,66,66,67,67,and 77 grams. let x be the weight of a randomly selected egg. what is the PMF of x?

Answer 1

Are these 12 eggs suppose to represent th ENTIRE population of eggs?

5 4
5 5
5 7
5 99
6 1
6 3
6 66
6 77
7 7

Looks like a bunch of p() = 1/12 and a few p() = 1/6

Answer 2

i think so. Im not completely confident what im even required to do for this question. am i suppose to get an equation or what?

Answer 3

Just list the probability masses:

p(54) = 1/12
p(55) = 1/12
p(57) = 1/12
p(59) = 1/6
etc...

Make sure it addes up to unity (1) when you are done.

Answer 4

and is that the entire PMF?

Answer 5

like that? but continue for the rest im assuming

Answer 6

...all the way to 77.

Answer 7

alright thank you
