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? 176 82 293 110 246 134 90 213 The range of the sample data is (Round to one decimal place as needed.) The standard deviation of the sample data is Round to one decimal place as needed.) The variance of the sample data is (Round to one decimal place as needed.) How useful are the measures of variation for someone searching for a O A. The measures of variation are not very useful because the values are nominal data that do not measure or count The measures of variation are very useful because a person does not want to buy a room where the variation is too low O C. The measures of variation are very useful because a person does not want to buy a room where the variation is too high O D. The measures of variation are not very useful because when searching for a room, low prices, location, and good accommodations are more important than O B. he amount of variation in the area 0 of 3 This course (MATH 1

Explanation / Answer

The range, standard deviation ,and variance can be found using the R statistical software. The code and output is given below:

x<-c(176,82,293,110,246,134,90,213)
> range(x)
[1] 82 293
> range<-293-80
> range
[1] 213
> sd(x)
[1] 77.27317
> var(x)
[1] 5971.143

Range =213

standard deviation=77.27

variance=5971.14

How useful the measures of variation for someone searching for a room?
