Step-by-step explanation: 1 Find the Least Common Denominator (LCD) of \frac{1}{4}, \frac{1}{3}, \frac{1}{6}, \frac{1}{8}, \frac{1}{8}

Method 1: By Listing Multiples

List out all multiples of each denominator, and find the first common one.

Multiples of 4 : 4, 8, 12, 16, 20, 24, ...

Multiples of 3 : 3, 6, 9, 12, 15, 18, 21, 24, ...

Multiples of 6 : 6, 12, 18, 24, ...

Multiples of 8 : 8, 16, 24, ...

Therefore, the LCD is 2424.

Method 2: By Prime Factors

List all prime factors of each denominator, and find the union of these primes.

Prime Factors of 4 : 2, 2

Prime Factors of 3 : 3

Prime Factors of 6 : 2, 3

Prime Factors of 8 : 2, 2, 2

Therefore, the LCD is 2\times 2\times 2\times 3=242×2×2×3=24.

LCD = 2424

2 Make the denominators the same as the LCD.

\frac{1\times 6}{4\times 6}+\frac{1\times 8}{3\times 8}+\frac{1\times 4}{6\times 4}+\frac{1\times 3}{8\times 3}+\frac{1\times 3}{8\times 3}

4×6

1×6

3×8

1×8

6×4

1×4

8×3

1×3

8×3

1×3

3 Simplify. Denominators are now the same.

\frac{6}{24}+\frac{8}{24}+\frac{4}{24}+\frac{3}{24}+\frac{3}{24}

4 Join the denominators.

\frac{6+8+4+3+3}{24}

6+8+4+3+3

5 Simplify.

\frac{24}{24}

6. Cancel 2/4 2/4.=

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
