The following values are obtained from a random sample that was drawn from a normally distributed population.

[1.95, 3.48, 1.85, 1.84, 2.7, 3.11]

If we are interested in creating a 90% confidence interval for σσ, the population standard deviation, then:

a)  Calculates, the sample standard deviation ands^2, the sample variance.

Round your responses to at least 6 decimal places.

s     =

s^2 =

b)  What are the values for the lower and upper limits of the confidence interval for the STANDARD DEVIATION σσ?

Round each of your values to at least 3 decimal places before entering them.
