[2.995, 9.281, 0.458, 2.261, 3.022, 3.610]. After rejecting/accepting the outlier, Report the mean and standard deviation of the dataset for both the 95% and 99% confidence scenarios.

Solution

In the sample given outlier = 9.281

Hence rejecting that we have other entries as

[2.995, 0.458, 2.261, 3.022, 3.610].

Mean =2.4692

Variance = 1.19435

Std dev = 1.09286

Confidence interval at 95% = 1.51 to 3.43

= (1.51, 3.43)

Confidence interval at 99% = 1.21 to 3.73

=(1.21, 3.73)
