![Instruction: Answer the questions completely. Show all pertinent solutions. No immediate rounding. Round off final answers to four decimal places. For final answers with less
than four decimal values, keep them as is. Use the statistical tables provided in class. Don't forget to define the parameters of interest.
You will submit your solutions on the second to the last page. Remember to click "Submit all and finish."
When computing the mean and variance (or standard deviation) using
X;
X = X;
1
1 N
1 N
(X; – 4)?
or o=
1
1
(X; – X)²
or s=
n-1 (X; – X)²
no need to show the formula and plugged-in values. You may use your calculator to directly compute for these.

![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:
