A cardiologist is interested in the average recovery period for her patients who have had heart attacks. Match the vocabulary word with its corresponding example.

1. All heart attack patients that the cardiologist has cared for or will care for in the future ⇒ B. POPULATION (entire group of individuals from where the sample must be chosen)

2. The 32 heart attack patients who were observed by the cardiologist ⇒ D. SAMPLE (the group that was observed)

3. The average recovery time for all heart attack patients that the cardiologist has or will treat ⇒ A. PARAMETER (the mean of the whole population)

4. The average recovery time for the 32 heart attack patients ⇒ E. STATISTICS (the mean of the sample)

5. The recovery time for a heart attack patient ⇒ F. VARIABLE  (the data's attribute or value)

6. The list of all 32 heart attack patients' recovery times ⇒ C. DATA (information collected form the sample)

$450 is the answer.

step-by-step explanation:

30% of 450 = 135
