Question

cholesterol levels were collected from patients two days after they had a heart attack and are the is table. find the mean, median, and mode. round to the nearest tenth, if necessary. cholesterol levels 273 275 337 358 253 152 334 184 285 260 295 236 175 167 210 242 303 343 360 360 353 162 329 310 342 281 235 251 the mean is the median is the mode is

Explanation:

Step1: Calculate the sum of all values

$273 + 275+337+358+253+152+334+184+285+260+295+236+175+167+210+242+303+343+360+360+353+162+329+310+342+281+235+251 = 7494$

Step2: Calculate the number of values

There are 28 values.

Step3: Calculate the mean

Mean = $\frac{7494}{28}\approx267.6$

Step4: Arrange the data in ascending order

$152, 162, 167, 175, 184, 210, 235, 236, 242, 251, 253, 260, 273, 275, 281, 285, 295, 303, 310, 329, 334, 337, 342, 343, 353, 358, 360, 360$

Step5: Calculate the median

Since $n = 28$ (even), median = $\frac{\text{14th value}+\text{15th value}}{2}=\frac{273 + 275}{2}=274$

Step6: Find the mode

The mode is 360 as it appears 2 times and no other value appears more frequently.

Answer:

The mean is 267.6
The median is 274
The mode is 360
