fourteen percent of male survey respondents reported having a diagnosis of cardiovascular disease.

Explanation:

Step1: Understand descriptive statistics

Descriptive statistics summarize and describe data.

Step2: Analyze each option

• Option 1: “Among older adults, the prevalence of cardiovascular disease is significantly greater in those with a history of type 2 diabetes than those without type 2 diabetes.” This involves a comparison and significance testing (inferential statistics).
• Option 2: “Women under 80 years of age with a family history of heart attack are at a fivefold increased risk for suffering a heart attack.” This is about risk assessment (inferential statistics).
• Option 3: “There is a moderately negative correlation of - 0.55 between daily physical activity level and cardiovascular disease.” Correlation analysis can be part of inferential statistics (testing relationships in the population).
• Option 4: “Fourteen percent of male survey respondents reported having a diagnosis of cardiovascular disease.” This simply describes a proportion of the sample (descriptive statistics).

Answer:

Fourteen percent of male survey respondents reported having a diagnosis of cardiovascular disease.
