Answer:

First, you would need to find a common denominator for the two, in this case it would be 6 which would make the equation 3/6 + 4/6=7/6. Then in order to make the answer a mixed number you would need to divide the numerator into the demonanator,  write down the whole number answer (6 will go into 7 ONE time) then write down the "leftovers". The final answer would be 1 1/6

(i hope this helps! im not the best at explaining)

A manufacturer of cell phone screens is concerned because 12 percent of the screens manufactured using a previous process were r
astraxan [27]

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
