Answer:
The complete 2-way table is given below.
Step-by-step explanation:
Denote the events as follows:
C = a high school student owns a cell phone
NC = a high school student does not owns a cell phone
P = a high school student owns a PS4
NP = a high school student does not owns a PS4.
The information provided is:
P NP Total
C 133 ___ 781
NC ___ 192 ___
Total ___ ___ 1000
Complete the table as follows:
n (C ∩ NP) = n (C) - n (C ∩ P)
= 781 - 133
= 648
n (NC) = N - n (C)
= 1000 - 781
= 219
n (NC ∩ P) = n (NC) - n (NC ∩ NP)
= 219 - 192
= 27
n (P) = n (C ∩ P) + n (NC ∩ P)
= 133 + 27
= 160
n (NP) = N - n (P)
= 1000 - 160
= 840
The complete 2-way table is:
P NP Total
C 133 648 781
NC 27 192 219
Total 160 840 1000
