Using RStudio, find the t-critical values for the following situations. Round your critical values to 3 decimal places.
Using RStudio, find the t-critical values for the following situations. Round your critical values to 3 decimal places. 1. \( \bar{x}=5, n=35, x=2.3 \), confidence level \( =95 \% \) t-critical value \( = \) 2. \( \bar{x}=5, n=35, s=2.3 \), confidence level \( =99 \% \) t-critical value \( = \) 3. \( \bar{x}=32, n=20, s=4.57 \), confidence level \( =90 \% \) t-critical value \( = \)
