Answer: 1. c. There are no differences in the mean completion times among the scents compared

2. Scent; Completion Time

Explanation:

The Null Hypothesis of a research is that hypothesis which you aim to disprove because it holds that no significant relationship between the variables being researched exists.

In this scenario you are studying whether scent affects spatial reasoning abilities.

The Null Hypothesis will.be that which states that there is no relationship between scent and spartial reasoning therefore there will be no differences in the mean completion times among the scents compared.

The factor of interest is the variable that is being changed to examine a difference making it the SCENT in this scenario.

The dependent variable changes due to the Factor of Interest so it is the COMPLETION TIME.

Ivenika [448]

Answer:

Instructions are listed below

Explanation:

Giving the following information:

The high-low method involves taking the highest level of activity and the lowest level of activity and comparing the total costs at each level.

Mountain has recorded the following for the past nine months:

January:

Number of Cavities= 375

Total cost= $5,300

February:

Number of Cavities  500

TC= 5,850

March

Number of Cavities 350

TC= 5,200

April

Number of Cavities 600

TC=6,250

May

Number of Cavities 325

TC= 5,150

June

Number of Cavities 475

TC= 5,700

July

Number of Cavities 525

TC= 6,100

August

Number of Cavities  575

TC= 6,300

September

Number of Cavities  450

TC= 5,550

A) Variable cost= (Highest activity cost - lowest activity cost) / (Highest activity units - lowest activity units)

Variable cost= (6300 - 5150) / (600 - 325)= 4.18 per unit

Fixed cost= HACost - (variable cost per unit * HAUnits)= 6300 - (4.18*600)= 3792

Fixed cost= LACost - (variable cost per unit* LAUnits)= 5150 - (4.18*325)= 3792

B)  Q= 400

Total cost= 3792 + 4.18*400= $5464
