im not exactly sure what you mean by that, could you please rephrase and expand on the pregunta
Step-by-step explanation:
Answer:
See explanation below
<u>Step-by-step explanation:</u>
range = 2200 - 300 = 1900
To find standard deviation, we have:
standard deviation = range/4 =
= 475
The range rule of thumb estimate for the standard deviation is 475
Given:
Standard deviation,
= 475
Margin of Error, ME = 100
= 1 - 0.90 = 0.10
Za/2 = Z0.05 = 1.64
Find sample size, n:
n ≥
n ≥
n ≥ 60.68
≈ 61
Minimun sample size,n = 61
Answer:
1a. -4 3/5
1b. -4 3/5
2. 33
Step-by-step explanation:
1a. -4 4/5 + 1/5 = -4 3/5
1b. -4 2/5 + (-1/5) = -4 3/5
2. (-16 -35) + 18 = -33
You would need to draw the number 33 to get a score of 0.
