Answer: 16
Step-by-step explanation:
Standard deviation is 2
Margin error for the problem is 1
Probability 95%, that means thet the siginficance level α is 1 – p
α = 1 – 0.95 = 0.05
margin of error (ME) can be defined as follows
ME = Z(α/2) * standard deviation/ √n
Where n is the sample size
Z(0.05/2) = Z(0.025)
Using a z table Z = 1.96
Now, replacing in the equation and find n
1 = 1.96 * 2/ √n
1 = 3.92 / √n
√n = 3.92
n = 3.92^2
n = 15.36 = 16
i hope this work for you
Answer:
1. 1 cup of concentrate would use 7.5 cups of water.
2. 10 cups of concentrate would use 75 cups of water.
Step-by-step explanation:
Because 1/3 cup of concentrate is mixed with 2 1/2 cups of water, to find how much water one cup of concentrate would use, you would have to multiply both 1/3 and 2 1/2 (2.5) by 3. Then, you get 1 cup of concentrate equals 7 1/2 (7.5).
To find the answer to the next question, simply multiply by 10.
Answer:
C. Strong Positive Linear Relationship
Step-by-step explanation:
If you were to draw a line through the points all of the points would be near the line therefore it has a strong correlation
The points are going upwards from left to right which indicates that the relationship is positive
From this information we can make a conclusion
This scatter plot has a strong positive linear relationship
