The answer is D. This is because all of the variables must be on one side so it can be factored.
Answer:
-9 + 5 = -4
Step-by-step explanation:
I think that's what your asking.....
Answer:
w = 5
y = 4
Step-by-step explanation:
w+y=9
3w-y=11
4w = 20
w = 5
y = 4
Null hypothesis: There is no significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected
.
Alternative hypothesis :There is a significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected
.
Finally the null hypothesis will be rejected and we should accept the alternate hypothesis
Step-by-step explanation:
In the existing process the sample size and population was not known.,but the percentage of rejected screens were given as 12%.,but in the new process out of 100 screens only 6 are rejected
percentage of rejected screens using new process = 6÷ 100 ×100 = 6%
percentage of rejected screens using existing (old) process = 12%
so the new process is the effective one which reduces the rejection rate of screens., hence it is concluded that There is a significant association between the existing process and the new process for reducing the population proportion of screens that will be rejected
.
so the null hypothesis will be rejected and we should accept the alternate hypothesis
