Question

low - density lipoprotein (ldl) is an important part of blood cholesterol test. ldl higher than 130mg/dl is a risk factor of developing cardiovascular disease. to prevent cardiovascular disease, a health center had a free blood cholesterol test for all the people older than 65 in the community. a total of eight people attended the blood screening and their blood test results are listed below: ldl(mg/dl): 130,143,114,110,123,110,134,124. after the blood test, the nurse wants to know the mode of ldl scores: a. 123 b. 130 d. 143 c. 110

Explanation:

Step1: Recall mode definition

The mode is the value that appears most frequently in a data - set.

Step2: Count frequencies

The data set is \(130,143,114,110,123,110,134,124\). The frequency of \(110\) is \(2\), the frequency of \(123\) is \(1\), the frequency of \(130\) is \(1\), the frequency of \(143\) is \(1\), the frequency of \(114\) is \(1\), and the frequency of \(134\) is \(1\), the frequency of \(124\) is \(1\).

Step3: Determine the mode

Since \(110\) appears \(2\) times and other values appear only \(1\) time, the mode is \(110\).

Answer:

C. 110
