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? 234 160 119 131 218 207 146 141 the range of the sample data is? the standard deviation of the sample data is? the variance of the sample data is? how useful are the measures of variation for someone searching for a room? a. the measures of variation are not very useful because when searching for a room, low prices, location, and good accommodations are more important than the amount of variation in the area. b. the measures of variation are very useful because a person does not want to buy a room where the variation is too low. c. the measures of variation are not very useful because the values are nominal data that do not measure or count anything, so the resulting statistics are meaningless. d. the measures of variation are very useful because a person does not want to buy a room where the variation is too high.

Range = 115$

Standard Deviation = 43.76$

Variance = 1915.142$

Option  A) The measures of variation are not very useful because when searching for a room, low prices, location, and good accommodations are more important than the amount of variation in the area.

Step-by-step explanation:

We are given the data for  prices in dollars for one night at different hotels in a certain region.

234, 160, 119, 131, 218, 207, 146, 141        

Range:

Sorted data: 119, 131, 141, 146, 160, 207, 218, 234

Standard Deviation:

where are data points, is the mean and n is the number of observations.  

Sum of squares of differences = 4160.25 + 90.25 + 2550.25 + 1482.25 +  2352.25 + 1406.25 + 552.25 + 812.25 = 13406

Variance =

Measure of variance for someone searching for room:

Option  A) The measures of variation are not very useful because when searching for a room, low prices, location, and good accommodations are more important than the amount of variation in the area.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

360/29
