The answer is < because 431,511 is more than 413,115
X + 8x = 81
9x = 81, x = 9
y = 8(9), y = 72
Solution: (9, 72)

(b) 41%
Step-by-step explanation:
We can simplify this problem down by realizing that the amount of girls over 200 will get us our percentage as a decimal.
Looking at this table, we can see that 
girls were asked. So, 
, and 
.
We can also see that 
people preferred video games, so

Answer:
True
Step-by-step explanation:
Assemble line is a production process in which parts are joined to the products produced as a partially finished product.
Here the process flow is discreet that is assembled one at a time.
Continous process flow is a type of manufacturing products without disruption of the flow process.
As the name implies,it is continous.
a. The standard error is equal to the standard deviation divided by the square root of the sample size:
SE = (23 ppm)/√18 ≈ 5.42 ppm
b. The t statistic is given by the difference between the true and sample means, divided by the standard error:
t = (192 ppm - 180 ppm)/SE ≈ 2.21
c. The p-value is approximately 0.0204.
d. Since p < 0.05, the difference is significantly different, so we reject the null hypothesis.
e. A type I error might have occurred, since it's possible that the null hypothesis was true, but we ended up rejecting it.
