3. Suppose you are a caseworker for Eldergarden, an agency that provides social services to the elderly. You are assigned to provide some descriptive statistics for the agency's caseload for the month.

a. Compute the mean, median, and modal age (column I of the table).

b. Compute the range of ages and use it to estimate the standard

deviation.
c. Compute the standard deviation of ages using both the direct and

shortcut methods.
d. Compare the answers to parts (b) and (c) and comment

***Do (a) through (d) of exercise 3 for case contacts in Past year (column IV of the table). (this is the question)***

Mean of stock price = 1117.64

STDEV (Population) = 67.61

1. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed within $50 of the mean for that year (round to two places)? (Hint: this means the probability of being between 50 below and 50 above the mean).

2. If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than $1050 per share (round to two places)? Would this be considered unusual? Use the definition that an unusual value is more than 2 standard deviations above or below the mean.

3. At what prices would Google have to close in order for it to be considered statistically unusual or statistically significant outliers? You will have a low and high value. There are several possible definitions for unusual in statistics, but for our project let's use the definition that an unusual value is more than 2 standard deviations above or below the mean.

Assessment:

Chief Complaint: 72-year-old woman who fell on her right hip.

History: 72-year-old white female, was brought to the Emergency Room after falling. She was previously in good health, despite leading a relatively sedentary lifestyle and having a 30-year history of cigarette smoking. The only medication she currently takes is propranolol for mild hypertension. She fell upon entering the bathtub when her right leg slipped out from under her; she landed on her right hip. There was no trauma to her head, nor does she complain of right or left wrist pain. However, she reports severe pain in the right hip and upper thigh and was unable to get up after her fall.

Physical examination: A/O x4, and was responding appropriately to questions despite being in considerable pain. There were no signs of trauma to the head, neck, torso, arms or left leg. The right thigh and hip were extremely tender and were immobilized by a leg splint. Heart and lung sounds were normal and abdominal sounds were reduced.

Radiology report: The X-ray of the right hip revealed a complete, comminuted, intertrochanteric fracture of the right hip. There were also long-term osteoporotic changes in the femur, tibia, and fibula.

Surgery: ORIF to the right hip

Following her recovery, she was placed on three medications: oral calcium supplements, oral estrogen, and oral alendronate sodium.  

Question:

1.    Why do bones become osteoporotic in some people?

2.    How does weight-bearing exercise influence the bone healing process?

3.    What risk factors does she have for osteoporosis?

4.    What bones are most vulnerable to osteoporosis and why?

5.    How does each of these medications work to treat the patient?

Thanks
