Question

listed below are prices in dollars for one - night at different hotels in a certain region. find the range, variance, and standard deviation for the given sample data. include appropriate units in the results. how useful are the measures of variation for someone searching for a room? 145 79 99 106 250 127 113 145 the range of the sample data is (round to one decimal place as needed.)

Explanation:

Step1: Identify maximum and minimum values

The data set is 145, 79, 99, 106, 250, 127, 113, 145. The maximum value $x_{max}=250$ and the minimum value $x_{min}=79$.

Step2: Calculate the range

The formula for the range $R$ of a data - set is $R=x_{max}-x_{min}$. So, $R = 250 - 79=171$.

Answer:

171.0 dollars
