Problem ①: Find the median for each set of data.

Step1: Sort data set A

Sort $49, 32, 67, 55, 58$ → $32, 49, 55, 58, 67$

Step2: Find median of A

Middle value (3rd term): $55$

Step3: Sort data set B

Sort $3.1, 5.2, 4.4, 5.0, 3.8, 2.6, 4.7$ → $2.6, 3.1, 3.8, 4.4, 4.7, 5.0, 5.2$

Step4: Find median of B

Middle value (4th term): $4.4$

Step5: Sort data set C

Sort $29, 12, 30, 22, 7, 23, 36, 15, 18, 9$ → $7, 9, 12, 15, 18, 22, 23, 29, 30, 36$

Step6: Find median of C

Average of 5th/6th terms: $\frac{18+22}{2}=20$

Step7: Sort data set D

Sort $81.6, 83.7, 78.5, 82.8, 81.2, 76.3, 83.5, 78.9$ → $76.3, 78.5, 78.9, 81.2, 81.6, 82.8, 83.5, 83.7$

Step8: Find median of D

Average of 4th/5th terms: $\frac{81.2+81.6}{2}=81.4$

Step9: Sort data set E

Sort $110, 115, 109, 110, 116, 113, 112, 116, 110, 106, 113$ → $106, 109, 110, 110, 110, 112, 113, 113, 115, 116, 116$

Step10: Find median of E

Middle value (6th term): $112$

Problem ②: Weekly salaries for 5 people

Step1: List salaries

Salaries: $\$45000, \$2000, \$1500, \$1100, \$400$

Step2: Calculate mean salary

Sum: $45000+2000+1500+1100+400=50000$; Mean: $\frac{50000}{5}=10000$

Step3: Sort salaries for median

Sorted: $\$400, \$1100, \$1500, \$2000, \$45000$

Step4: Find median salary

Middle value (3rd term): $1500$
---

Problem ③: Find the mode(s)

Step1: Count suit sizes (A)

Most frequent: $37, 39, 40$ (each 4 times)

Step2: Count dash times (B)

Most frequent: $6.7$ (4 times)

Step3: Count runs scored (C)

Most frequent: $5$ (6 times)
---

Problem ④: Typing speeds (12 students)

Step1: List speeds

Speeds: $31,27,15,31,24,13,30,24,18,35,28,24$

Step2: Calculate range (A)

Range: $35-13=22$

Step3: Calculate mean (B)

Sum: $31+27+15+31+24+13+30+24+18+35+28+24=300$; Mean: $\frac{300}{12}=25$

Step4: Sort speeds for median (C)

Sorted: $13,15,18,24,24,24,27,28,30,31,31,35$; Median: $\frac{24+27}{2}=25.5$

Step5: Find mode (D)

Most frequent: $24$ (3 times)

Problem F: Zark VII game prices

Step1: List prices

Prices: $41.75,43.89,42.50,43.40,42.95,40.69,42.90,40.50,39.95,45.30$

Step2: Find range

Range: $45.30-39.95=5.35$

Step3: Calculate mean

Sum: $41.75+43.89+42.50+43.40+42.95+40.69+42.90+40.50+39.95+45.30=423.83$; Mean: $\frac{423.83}{10}=42.383\approx42.40$

Step4: Sort prices for median

Sorted: $39.95,40.50,40.69,41.75,42.50,42.90,42.95,43.40,43.89,45.30$; Median: $\frac{42.50+42.90}{2}=42.70$
