Answer:
The potato bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn chip bag assembly line.
Step-by-step explanation:
Popcorn mean= μ`1= 3.06
Popcorn St. Dev= σ1= 0.02
Potato Mean= μ`2= 5.05
Potato St. Dev= σ2= 0.05
Finding the z score
z= x- u / σ
Popcorn z= 3.06- 3.03/0.02= 1.5
Potato Z= 5.05-5.07/0.05= -0.4
The mean is taken to be at zero ( 0) therefore difference of 0.4 is less than a difference of 1.5
Choice 3 is the best option .
1/4 2/8 3/12 4/16 5/20 6/24
Answer:
153.158 ; 177.642
Step-by-step explanation:
Given the following:
Sample mean (m) = 165.40
Sample standard deviation (s) = 21.70
Sample size (n) = 17
α = 98%
Confidence interval = m ± z(SE)
z at 98% = 2.326
SE = s/√n
SE = 21.70/√17 = 5.2630230
Hence,
Confidence interval = 165.40 ± 2.326(5.2630230)
165.40 - 12.241791498 OR 165.40 + 12.241791498
153.158 ; 177.642
Answer:
D
Step-by-step explanation:
We need to graph both 
and 
and figure out <em>the x-value at which the graph of is LESS THAN that of the graph of .</em>
<em />
The attached picture shows the graph of in BLUE and the graph of in RED.
<em><u>We need to find x-value where the BLUE graph is "BELOW" the RED graph.</u></em> We can see that this occurs when x < 0.
Thus the correct answer is D
