**Question 1**Find the critical value $ t_{\frac{\alpha}{2}} $ corresponding to a 99% confidence level, given that the sample has size $ n = 21 $.Options:- $ 1.428 $- $ 1.28 $- $ 2.831 $- $ 2.845 $---This question requires choosing the appropriate critical value for a t-distribution. To find this, one usually refers to a t-table or uses statistical software, considering the degrees of freedom (sample size minus one) and the confidence level specified.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
