The simplified version of this equation is 8
25 % = 18
50% = 36
75 % = 54
100 % = 72
25% x 72 = 18 therefore n = 72
125% x 72 = 90
Therefore 125% of n is 90
Answer:
(13.5, 34.5)
Step-by-step explanation:
The empirical rule states that for a normal distribution, the data will fall within three standard deviations of the mean. 68% of the data falls within the first standard deviation (µ ± σ), 95% within the first two standard deviations (µ ± 2σ), and 99.7% within the first three standard deviations (µ ± 3σ).
Given that mean (µ) = 24 and standard deviation (σ) = 3.5
Using empirical rule, the interval that represents the middle 99.7% = (µ ± 3σ) = (24 ± 3*3.5) = (13.5, 34.5)
Um could you clarify the equations seperartly. its all one big equation
