FINALLY SOMEONE WANTS TO HELP ME D:

Answer 3

let me try...never solved such problem before :P

Answer 4

Here, use this for reference

Answer 5

The four-step statistical process might require data that has two categories. A two-way frequency table shows the frequencies for data that has two categories.
A joint frequency is found by reading from the inner cells of a two-way frequency table. Look at the row title and the column title to find the two categories for each joint frequency.
The sums for each row and column are shown as marginal frequencies. Marginal frequencies are found on the outside edges of the table (in the last row and the last column).
A relative frequency table shows each frequency as a proportion of the whole data sample size.
A joint relative frequency is found by dividing a joint frequency by the whole sample size.
A marginal relative frequency is found by dividing a marginal frequency by the whole sample size.
A conditional relative frequency shows a frequency proportion for a given condition or category. For example, if you are given a specific category (in a row or column), what do the other categories show? This is helpful when looking for trends or associations in the data. A conditional relative frequency is found by dividing a joint frequency by a marginal frequency. Two tables are needed to display the calculations for conditional relative frequencies:
One table to show row categories
Another table to show column categories

Answer 6

My notes ^_^

Answer 7

Let me repaste that

Answer 8

i am supposed to read that :O

Answer 9

Not necessarily

Answer 10

If you want to :>

Answer 11

b and c?

Answer 12

Yes, B and C

Answer 13

I am thinkign its B or C, I can't make up my mind

Answer 14

A conditional relative frequency is found by dividing a joint frequency by a marginal frequency.

Answer 15

Yes, sir

Answer 16

80/280
200/280

Answer 17

oh for jazz, difference is 0

Answer 18

So, it looks like it would be C, then

Answer 19

no..thats exactly my point
0 is not smallest
the difference could be negative too

Answer 20

Ohh

Answer 21

but the largest difference would be for pop only, no doubt in that

Answer 22

So that answer is B

Answer 23

yep, i think so....and hope so :)
