Answer:
7f/z
Step-by-step explanation:
mat h wAyz
27mi/60min=9/20
9mi/20min=xmi/1min
Cross multiply
Divide by 20 on both sides

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
