Since 5 + 9 is 14 you can use ANY expression that has the same final value/ sum
Answer:
From the frequency table, let's calculate the row total.
Row total for phone call = 19 + 9 = 28
Row total for no phone call = 8 +6 = 14
To calculate their respective row relative frequencies, let's use:
Row relative freq =
Now, the two-way frequency table will be computed as:
For phone call:
Desirable behavior =
≈0.69
Undesirable behaviour =
≈0.32
No phone call:
Desirable behaviour =
≈ 0.57
Undesirable behaviour =
≈ 0.43
The complete two-way table is attached.
Answer:
This answer would be c
Step-by-step explanation:
Answer:
1/16 of the class are left handed boys but we do not know the amount of left handed girls so we cannot be sure.
Step-by-step explanation:
1/2 * 1/8 = 1/16
there is still no way to be sure of how many girls are left handed so you should probably make a note by the problem so the mistake on the test will be realized
