$\begin{array}{cccccc}{Mean} & {1.5} & {2} & {2.5} & {3} & {3.5}\ \\ {Probability} & {\frac{1}{6}} & {\frac{1}{6}} & {\frac{1}{3}} & {\frac{1}{6}} & {\frac{1}{6}}\ \end{array}$

Explanation:

Given

$Cards = \{1,2,3,4\}$

Required

The sampling distribution

The possible selection of 2 cards without replacement is as follows:

$S = \{(1,2) (1,3) (1,4) (2,1) (2,3) (2,4) (3,1) (3,2) (3,4) (4,1) (4,2) (4,3)\}$

Calculate the mean

$\begin{array}{cccccccccccc}{Selection} & {(1,2)} & {(1,3)} & {(1,4)} & {(2,1)} & {(2,3)} & {(2,4)}& {(3,1)} & {(3,2)} & {(3,4)} & {(4,1)} & {(4,2)} & {(4,3)} \ \\ {Mean} & {1.5} & {2} & {2.5} & {1.5} & {2.5} & {3} & {2} & {2.5} & {3.5} & {2.5} & {3} & {3.5}\ \end{array}$

List out the mean and the respective frequency

$1.5 \to 2$

$2 \to 2$

$2.5 \to 4$

$3 \to 2$

$3.5\to 2$

$Total \to 12$

Calculate the probability of each mean

$P(1.5) \to \frac{2}{12} \to \frac{1}{6}\\$

$P(2) \to \frac{2}{12} \to \frac{1}{6}\\$

$P(2.5) \to \frac{4}{12} \to \frac{1}{3}\\$

$P(3) \to \frac{2}{12} \to \frac{1}{6}\\$

$P(3.5) \to \frac{2}{12} \to \frac{1}{6}$

So, the table of sampling distribution is:

$\begin{array}{cccccc}{Mean} & {1.5} & {2} & {2.5} & {3} & {3.5}\ \\ {Probability} & {\frac{1}{6}} & {\frac{1}{6}} & {\frac{1}{3}} & {\frac{1}{6}} & {\frac{1}{6}}\ \end{array}$

Genevieve (Genny) Osaka, 14 m/o infant female; MVA at 4 m/o causing C4 spinal fracture and SCI, lives w/ mom, has trach and on m

MrRissso [65]

The question is asking for a detailed explanation of the case of Genevieve (Genny) Osaka, a 14-month-old infant female who was involved in a motor vehicle accident (MVA) at 4 months of age, resulting in a cervical spine fracture at the C4 level and a spinal cord injury (SCI).

<h3>What are some points to note?</h3>

Some possible points to include in the answer are:

A C4 spinal fracture is a break in the fourth cervical vertebra, which is located in the neck region of the spine. This can damage the spinal cord, which is the bundle of nerves that carries signals between the brain and the rest of the body.

A tracheostomy (trach) is a surgical procedure that creates an opening in the neck to access the trachea. A trach tube is inserted into the opening to allow air to pass in and out of the lungs. A trach can help a person breathe more easily, prevent airway obstruction, and reduce the risk of infections and complications from long-term mechanical ventilation.

A J-tube is a type of feeding tube that is surgically placed into the jejunum, which is the middle part of the small intestine. A J-tube can deliver liquid nutrition and medications directly into the digestive system, bypassing the mouth, throat, and stomach. A J-tube can help a person who has difficulty swallowing, has a risk of aspiration, or has poor nutritional status.

Genny lives with her mom, who is her primary caregiver. Her mom is responsible for managing her trach care, mechanical ventilation, J-tube feedings and medications, and other aspects of her daily care. Her mom also has to cope with the emotional, financial, and social challenges of having a child with a severe disability.

Genny's mom is finalizing things for childcare, which means she is looking for a suitable and reliable person or facility that can take care of Genny while she is away for work or other reasons. Finding childcare for a child with complex medical needs can be difficult, as it requires specialized training, equipment, and resources.

Genny's mom may also have to consider the cost, availability, quality, and safety of the childcare options. She may also have to coordinate with Genny's healthcare team, insurance company, and social services to arrange for the appropriate level of care and support for Genny and herself.
