Exercise template for computing the 2-sided confidence interval (with extended Moodle processing) for the mean based on a random sample.

Name:
confint3
Description:
Computing the 2-sided confidence interval at 95% level for the mean based on a random sample. The exercise is a cloze with two numeric answers for the lower and upper bound of the confidence interval, respectively. Using the ‘verbatim’ clozetype for Moodle, the exercises yields 100% of the points for the correct solution based on t quantiles but still 50% for a partially correct solution based on normal quantiles.
