Answer:

9 ( 2x - 1 )

Step-by-step explanation:

→ Look for the HCF of the whole numbers

HCF of 18 and 9 is 9

→ Put 9 outside the brackets

9 ( ? - ? )

→ Perform the calculation 18x ÷ 9 to determine the first question mark

18x ÷ 9 = 2x ⇔ 9 ( 2x - ? )

9 ÷ 9 = 1 ⇔ 9 ( 2x - 1 )

Step-by-step explanation:

Given that in our industry on average a firm paid out record year end bonuses of $125,500 per employee for 2008. We would like to take a sample of employees at our firm to see whether the mean year end bonus is different from the reported mean of $125,500 for the population.

1. Sample Mean = 118000

2. Population Mean = 125500

3. Population Standard Deviation = 30000

4. Sample size = 40

5. Alpha Error = 5%

6. Confidence Coefficient = 95%

7. Calculate Test Statistic = Mean difference /s td error = -1.581

8. Rejection Region Critical Value = If Z statistic is below -1.96 or above 1.96
