Step-by-step explanation:
n-8≤17
add 8 on both sides to isolate the variable.
n is less than or equal to 25
Answer: i would say probably 3 or -3
I hope it helps
Answer:
<h2>- 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept
We have
Therefore the slope is equal to -2.
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
