Empirical rule dictates that, in a Bell-shaped distribution, 95% of data lies within 2 standard deviation on either side of the mean.
Therefore,
Lower value = mean-2SD = 70-2*8 = 70-16 = 54
Upper value = mean+2SD = 70+2*8 = 70+16 = 86
Then, 95% of the data lies between $54 and 84. These values can also be taken as the true mean of the population considering 95% confidence when sample mean has been calculated. In this regard, 2SD can be regarded as the margin error.
Answer:
im about to solvee
Step-by-step explanation:
1. B
because 180 degrees minus 110 would be 70
Answer:
63
Step-by-step explanation:
Basically [x=8] when a letter (x) is directly by a number.
(8 × 8) - 1 = 64 - 1 = 63
8 × ? = (8 × 8) and 8 as in (x) then you can finish the question.
