Question

Total blood cholesterol level was measured for each of 10 adults. Here are the 10 measurements (in mg/dL).176, 251, 247, 262, 150, 214, 192, 194, 154, 255Send data to calculator(a) What is the mean of this data set?

Answer 1

Answer:

a) 209.5mg/dL

b) 204mg/dL

c) zero modes

Explanations:

Mean is also known as average of a dataset. Given the data expressed below;

$Mean=\frac{sum\text{ of data}}{sample\text{ size}}$

Given the following parameters

Sum of data = 176 + 251 + 247 + 262 + 150 + 214 + 192 + 194 + 154 + 255

Sum of data = 2095

Sample size = 10 (Total measurement)

Determine the mean of the data

$\begin{gathered} Mean=\frac{2095}{10} \\ Mean=209.5 \end{gathered}$

Therefore the mean of the data is 209.5mg/dL

b) The median of the dataset is the value in the middle after rearrangement. On rearranging in ascending order;

150, 154, 176,192, (194, 214), 247, 251, 255, 262

The two values at the middle are 194 and 214.

$\begin{gathered} Median=\frac{194+214}{2} \\ Median=\frac{408}{2} \\ Median=204 \end{gathered}$

c) The mode of the data is the value that occur the most in the dataset. SInce all the data only appear once in the dataset, hence there are ZERO MODES
