Two competing brands, Rain and Shine, produced two different latex paints and planned to sponsor a home makeover by Marie Condo TV (MCTV). While thankful for these two sponsorships, MCTV producers wish to partner with the brand with the most consistent drying times since, based on experience, some paints from another brand dry fast while some dry longer than expected even if the paints came from the same brand. Fourteen specimens from Rain and sixteen specimens from Shine were collected, and their drying times (in hours) are as follows: Rain Shine 3.5 4.7 2.7 3.9 3.9 4.5 4.2 5.5 3.6 4.0 2.1 5.3 3.8 4.3 5.2 6.0 4.2 5.2 2.9 3.7 4.4 5.5 5.2 6.2 4.0 5.7 4.1 5.4 4.8 4.4 Assuming that the drying time is normally distributed, construct a 95% Cl to determine which paint brand produced more consistent drying times.
