The formula Arya stark will use to find the 95% confidence interval is normal approximation of the distribution.
What is termed as the confidence interval?
- A confidence interval shows the likelihood that a parameter would then fall between two values near the mean.
- The amount of uncertainty as well as certainty inside a sampling method is measured by confidence intervals.
- They are also used to test hypotheses and perform regression analysis.
For the given question, the data is-
- Mean μ = 50
- Standard deviation σ = 4
- Confidence interval 95%
- Sample size n = 10.
- Sample mean = x
The formula for finding the 95% confidence interval is normal approximation of the distribution.
z = (x - μ)/s
Where, s = σ/√n
The corresponding value of z for 96% is taken from the z score table.
Thus, formula Arya stark will use to find the 95% confidence interval is normal approximation of the distribution.
