X^-3
Anything to the power of 0 is 1 so
X^-3/1= X^-3
Answer:
standard deviation = ±0.4667
Step-by-step explanation:
In Normal distribution, approximately 68% of all the data lie within 1 standard deviation from the mean, approximately 95% of all the data lie within 2 standard deviations from the mean and approximately 99.7% of all the data lie within 3 standard deviations from the mean.
Therefore, for a confidence interval of 99.7% the standard deviation of the x¯ must be 3 standard deviations from the mean,
3σ = ±1.4
σ = ±1.4/3
σ = ±0.4667
Therefore, 0.4667 is the standard deviation that x¯ must have so that 99.7% of all samples give an x¯ within 1.4 point of μ.
