Answer:

Step-by-step explanation:

1. Make 1 2/7 an improper fraction = 9/7

2. Multiply 7 on both numerator and denominator for 2/3 to make 14/21, and multiply 3 for both numerator and denominator for 9/7 to make 27/21.

3. Add them together. 14/21+27/21=41/21.

4. (Optional) If the question is asking for mixed numbers, 41/21 = 1 20/21.

Answer:

Claim : The amount UMSL students study is different from this 14.6 hour benchmark.

The hypotheses used in this situation

$H_0:\mu = 14.6$

$H_a:\mu \neq 14.6$
