1. Determine individual rates of work:
\text{Monice's rate} = \frac{1}{5} \text{ fence per day}
\text{Mike's rate} = \frac{1}{4} \text{ fence per day}

2. Combine rates of work:
\frac{1}{T} = \frac{1}{5} + \frac{1}{4}
\frac{1}{T} = \frac{4}{20} + \frac{5}{20}
\frac{1}{T} = \frac{9}{20}

3. Solve for \( T \):
T = \frac{20}{9} days

4. Simplify to a mixed number:
T = 2 \, \frac{2}{9} \text{ days}

5. Approximate value:
T \approx 2.22 \text{ days}

The answer is: T = 2 \, \frac{2}{9} \text{ days} (approximately 2.22 days)

A box of numbered pens has 12 red, 12 blue, 12 green and 12 yellow pens. The pens for each colour are numbered from 1 to 12. There is a unique number on each pen, so no pen is exactly the same as any other pen in the box. When reaching into the box to randomly draw five pens without replacement, what is the proportion of getting exactly four pens of the same colour (Note: the numbers matter but the order does not)?
Engineers want to design seats in commercial aircraft so that they are wide enough to fit ​95% of all males.​ (Accommodating 100% of males would require very wide seats that would be much too​ expensive.) Men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 1.2 in. Find P95. That​ is, find the hip breadth for men that separates the smallest ​95% from the largest 5​%.

We plan to test whether the mean mRNA expression level differs between two strains of yeast, for each of 8,000 genes. We will measure the expression levels of each gene, in n samples of strain 1 and m samples of strain 2. We plan to compute a P-value for each gene, using an unpaired two-sample t-test for each gene (the particular type of test does not matter). a) What are the null hypotheses in these tests (in words)? [2] b) If, in fact, the two strains are identical, how many of these tests do we expect to produce a P-value exceeding 1/4? [2]
