History Her chief complaint is P! behind her R medial malleolus. She tells you that the P! has been present for approximately two weeks. She does not remember a specific MOI. The P! increases with exercise (distance running) and persists for a few hours after exercise. In the past 48 hours, she has noticed mild P! at night. She has recently increased her mileage from 35 miles to 48 miles per week.  She reports no P! in her foot. She does not remember having any unusual sensations. She reports that she sprained her R ankle once in high school but she does not remember exactly what structures were injured.  AT RESPONSE: Based on the patient’s history, what corresponding conditions are you considering in the first step of differential diagnosis?  DIRECTIONS: Bullet your individual text entries. Your entries must be concise, specific, and accurate. Your entries must include correct spelling.  You may (and are encouraged) to use common abbreviations and acronyms linked to anatomical and medical terminology when appropriate.

Is there a relationship between the heights of fathers and their firstborn biological daughters?  To answer this, I randomly chose 11 measurements from an actual data set*.  The linear correlation coefficient between the height of the father and the height of the firstborn daughter is 0.431. The mean height of the fathers was 69.1 inches and the mean height of the daughters was 65.0 inches.  The linear regression equation for the data is Daughter = 32.7+0.47(Father), using Daughter and Father instead of y and x. Is there sufficient evidence of a linear correlation between the height of a father and his firstborn biological daughter?  Use a 0.05 significance level and thoroughly support your answer using the table below.  Find the best prediction of the height of a daughter if the father is 70 inches tall.  Do not round. *Actual data listed in the your textbook from the journal of Francis Galton (1822-1911), initiator of the ideas of standard deviation, regression line and correlation.
