Question

Total blood cholesterol level was measured for each of

8 adults. Here are the 8
measurements (in mg/dL):
264, 191, 160, 148, 262, 212, 268, 246

Answer 1

Answer: Mean = 218.9.

Median = 229

Mode = Zero mode.

Step-by-step explanation:

Given blood cholesterol level was measured for each of 8 adults (in mg/dL) are:

264, 191, 160, 148, 262, 212, 268, 246

In order to find the mean, we need to add all those 8 numbers and divide by 8.

Therefore, mean =
`(264+191+160+148+262+212+268+246)/(8) =(1751)/(8) =218.9.`

Mean = 218.9.

In order to find the median, we need to arrange them in ascending order:

148, 160, 191, 212, 246, 262, 264, 268.

The middle most two values are 212 and 246.

Therefore, median =
`(212+246)/(2) =(458)/(2) = 229.`

Median = 229.

`\mathrm{The\:mode\:is\:the\:term\:in\:the\:data\:set\:that\:appears\:the\:most.}`

`\mathrm{If\:there\:is\:more\:than\:one\:term\:that\:appears\:the\:most,\:then\:there\:is\:no\:mode.}`

`\mathrm{Count\:the\:number\:of\:times\:each\:element\:appears\:in\:the\:list}`

`\begin{pmatrix}148&160&191&212&246&262&264&268\\ 1&1&1&1&1&1&1&1\end{pmatrix}`

`\mathrm{The\:most\:common\:element\:is\:not\:unique,\:so\:there\:is\:no\:mode}`

Therefore, Mode = Zero mode.
