Answer: a. 2.8

Explanation:

Given : Population mean : \mu=\$6,000\text{ per day}

Sample size : n= 49> 30 , the sample is a large sample  we use z-test.

Sample mean = \overline{x}=\$6,400\text{ per day}

Standard deviation : \sigma= \$1,000

The test statistic for population mean is given by :-

z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\\Rightarrow\ z=\dfrac{6400-6000}{\dfrac{1000}{\sqrt{49}}}=2.8

Hence, the value of the test statistic is 2.8

PIT_PIT [208]
If the survey found that in every 320 people, 180 of them voted in favor of gas tax .Then to get the total number of people who voted in favor of gas tax were 36,000. We can get the number of 180 people groups among those who voted in favor. = 36,000/180 = 200 groups
A group of 180 people who voted in favor is equivalent to a group of 360 people who voted. 
Therefore, 200 × 360 people =72,000 people took part in the voting exercise.

Kermit's Hardware's (KH) fixed operating costs are $20.8 million and its variable cost ratio is 0.30. The firm has $10 million i
motikmotik

Answer:

Option (a) is correct.

Explanation:

EBIT:

= Revenues - Fixed operating costs - (variable cost ratio × revenues)

= $32.2 - $20.8 - (0.30 × 32.2)

= 1.74  million

KH's degree of total leverage:

= (EBIT + Fixed cost) ÷ (EBIT - Interest)

= (1.74 + 20.8) ÷ [(1.74 - (9% × 10)]

= 26.83

Therefore, the KH's degree of total leverage is 26.83.

Sauron [17]

Answer: Vroom and Yetton's normative decision model.

Explanation:

The Vroom–Yetton normative decision model is a situational leadership theory of industrial and organizational psychology that was developed by Victor Vroom, in collaboration with Phillip Yetton and later with Arthur Jago. The situational theory argues the best style of leadership is contingent to the situation.

Regarding decision making, the Vroom-Yetton model suggests that being autocratic, seeking advice, considering alternative approaches before a decision is made, informing a group on an issue, and letting that group develop the solution without forcing your own ideas are all important at times.
