Math Problem Statement
Assuming that the population is normally distributed, construct a 95% confidence interval for the population mean, based on the following sample size of n = 6. 1, 2, 3, 4, 5, and 19 ₽ In the given data, replace the value 19 with 6 and recalculate the confidence interval. Using these results, describe the effect of an outlier (that is, an extreme value) on the confidence interval, in general. Find a95% confidence interval for the population mean, using the formula or technology. ?≤mμ≤? (Round to two decimal places as needed.)

Formulas
Sample mean (x̄) = (Σx) / n
Standard deviation (s) = sqrt((Σ(x_i - x̄)^2) / (n - 1))
Confidence interval = x̄ ± t_(α/2) * (s / sqrt(n))
