Joshua must have 7 more customers if they each buy 2 items.
Answer:
Option C.
Step-by-step explanation:
Given information:
Sample size = 150
Number of Opinions = 3 (Yes, No, No Opinion)
Yes = 40
No = 60
No opinion = 50
We need to find the expected frequency for each group.
Expected frequency for each group is the quotient of sample size and number of opinions.



Therefore, the correct option is C.
M+n+3+m+n+4
=3m+2n+7
answer
C. 3m+2n+7
