Question

Please help me with this question, I'm not sure how to find what P1 is :> Thank you :3 I will give you a shiny medal :3 :>

Answer 1

whats the question

Answer 2

and what do yo need help calculating?

Answer 3

I want to find the expected value, but I don't know what the probability is for the question :<

Answer 4

expected count is pi (n) = E

Answer 5

look at your H0

Answer 6

it says its uniformally distrubuted

Answer 7

so the probability is 25% for each category

Answer 8

H0​: The distribution of hockey​ players' birth months is uniformly distributed.
H1​: The distribution of hockey​ players' birth months is not uniformly distributed.

Answer 9

so you just count the totla number and take 1/4 of that

Answer 10

why is it 1/4 (25%)? Is it because of the months?

Answer 11

yes, and to be more accurate, it because there are 4 categories

Answer 12

so: January-March is one category 1
​April-June is the second category 2
​July-September is the third category 3
​October-December is the forth category?

Answer 13

yes, and because each category must have equal probability accroding to H0, each of them is a 25%
