In a test of the effectiveness of garlic for lowering​ cholesterol, 36 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes​ (before minus​ after) in their levels of LDL cholesterol​ (in mg/dL) have a mean of 0.7 and a standard deviation of 20.1. Use a 0.10 significance level to test the claim that with garlic​ treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic​ treatment? Assume that a simple random sample has been selected. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative​ hypotheses?

Determine the test statistic.

Determine the​ P-value.

Toflokpo-Crane is new company that specializes in designing and manufacturing small-scale automatic jib cranes for moving heavy loads around a workshop or production line environment. Their primary selling point is the integration of neural network-based imaging technology to enable fully automatic identification of objects to pick-up, removing the need for human intervention. The primary components of a jib crane are the floor mounted pillar (containing a rotational motor), the jib/boom mounted on-top of the pillar, the customisable hoist that can traverse the jib/boom as well as raise or lower a pick-up attachment, the pick-up attachment that allows the crane to connect with the goods to move, the high-definition camera array that monitors the area under the pick-up attachment, and the AI unit that processes the camera input and directs the crane. Most pillars are of fixed height; however, the user can manually adjust the height for some pillars using a handle positioned at the pillar base.

Toflokpo-Crane engineers are awarding you the project of developing the software control system for the crane. There are two ways that the crane should be controlled. First, an on-floor administrator should access a crane control panel enabling manual control of the crane via a Web interface hosted by the crane (accessible via the local Wi-Fi network). They can also toggle between manual and autonomous mode, as well get a live feed from the camera arrays using the Web interface. The camera arrays are only powered when in use. If in autonomous mode, the crane will be controlled by the AI Unit, based on input from the camera array. The AI Unit and human operator share the same operations. Internally, the control system needs to send requests to the other crane components to facilitate pick-up and movement/drop-off of goods. The pillar can rotate a given number of degrees and the hoist can move a number of inches forward or backward along the jib, as well as raise/lower the attachment a number of inches. The Hoist knows the length of the Jib to avoid traversing further than the length of the Jib. The control system should support different attachments natively, as all available attachments share the same base set of commands. Toflokpo-Crane currently makes attachments for picking up packing crates and goods bags. In emergencies the crane can be shut down using a red stop button on the pillar.

Red Red Wine is a wine bar that has been incorporated by Amie. It operates as a closelyheld corporation. The other shareholders are Amie’s brother and sister-in-law. Amie runs the day-to-day management of the wine bar, including managing the books and records. Amie’s brother and sister-in-law handle distribution, sales and marketing. After a few years, Amie starts to feel like she is doing the majority of the work and becomes bitter about the business relationship. She feels like she should be earning more money for the amount of work she does for the bar. Without discussing it with her brother and sister-in-law, Amie starts taking an additional draw from the wine bar every month in the amount of $1,000. She deposits the money into a business account for an LLC she created. On the books and records of the wine bar, Amie records this amount to the LLC as a “consultation fee.” Can Amie be held personally liable in this situation? If so, why?

1. A man is jogging in Estes Park, Colorado. A mountain lion starts to track him. The man senses something behind him, looks back, and sees the mountain lion. The jogger springs into action and starts running as fast as he can go. He runs to a tree and climbs up.

Name and describe 3 psychobiological factors that may be operating in this situation. Explain what each is doing.

1. All @ 8.3

2.

3.

2. The mountain lion stands up against the tree growling ferociously and roaring, while trying to swat the jogger with its powerful paws.  

The jogger is desperately afraid. He reaches for a nearby branch, breaks it off, and tries to hit the mountain lion. He is trying to keep it from climbing up the tree. He swings the branch, occasionally hitting a paw or a leg, and screams curses at the mountain lion. The jogger does not notice that the temperature is dropping. The lion continues its attempts to reach the jogger. The man looks down at the lion as it roars, revealing long, wicked looking, cat’s teeth.

Name and describe 3 psychobiological processes that the jogger is experiencing.

  

3. The jogger’s wife, knowing how long his run should take, realizes that her husband is late. She becomes increasingly upset and worried. After an hour, she can’t wait any longer, calls the sheriff, and explains her concern. She can’t leave the house because there is an infant. Her hands are shaking as she tells the sheriff her husband’s favorite jogging route.  

How would you explain in 3 psychobiological terms what the jogger’s wife has been experiencing?

1.

2.

3.

4. The sheriff follows the jogging route and arrives at the scene. He sees the Mt. Lion standing up against the tree below the jogger. He immediately understands what is going on. He quickly pulls his riffle from the bracket in his Jeep, aims instinctively, and fires, killing the mountain lion. The grateful jogger climbs down. The sheriff wraps a blanket around him and drives him home.

On the ride back to his house, the jogger feels his body calming down as he distances himself to the extent he can from the extreme physical and mental ordeal. As they approach the jogger’s house, he realizes for the first time that it is very cold outside, and he is wearing only shorts and a tee shirt.  

Shortly after arriving home, he falls asleep on the couch while looking at his baby.

Describe three psychobiological processes that could be in effect for the jogger after the Mt. Lion has been killed and he has left the tree.

3.

Extra Credit

Answer these questions. You have nothing to lose!

5. The next day the jogger and his wife return to the scene of the fearful experience. He has told his wife about how he broke off the dead branch and tried to defend himself. The jogger says, for about the fifth time, that this had been the most terrifying experience in his life. As they approach the tree, he begins to feel uneasy.

He is amazed to see that the branch he broke off is almost 3 inches in diameter was alive and healthy. He wonders how he could have had the strength to break a branch that large and heavy.  

READ THIS QUESTION CAREFULLY!  

YOU ARE INSTRUCTED TO

OFFER A POSSIBLE EXPLANATION TO THE JOGGER.

Reader, how would you begin to explain to the jogger what psychobiological

Processes (3) had been triggered in him that may have accounted for the great

physical strength that enabled him to break off the branch that probably saved

his life?

Everybody, except of course the mountain lion, lives happily ever after.

A student decides to synthesize 3-methylbutene by an acid catalyzed dehydration of isoamyl alcohol. On heating, instead of collecting a liquid with a boiling point of 20 degrees celcius as expected, the student instead collects a liquid which boils at 100 degrees celsius, followed by another which boils at 173 degrees celsius. When added to an aqueous solution of Br2, neither liquid turns the solution clear. Explain in detail what went wrong, and identify the two products of the student's reaction.
