In order to compare the means of the two different locations, it must first be determined whether the standard deviations of the two locations are different For each location, calculate the standard deviation and report it Location 1 Location 2 (% C) 40.40 40.30 40.30 40.40 40.20 with two significant figures Location 1 (% C) 40.10 40.90 40.30 40.70 40.30 Location2 Number Number 4 what is the calculated F value for comparing the standard deviations? Number Are the two standard deviations for the locations significantly different at the 95% confidence level? O yes no Scroll down Previous Give Up & View Solution O Check Answer Next Exit Hint about uscareersprivacy policy tern

Explanation / Answer

Standard deviation for location 1=0.074

Standard Deviation for location 2=0.293

Calculated f value=0.293×0.293÷0.074×0.074=15.67

Therefore f value =15.6

Of course yes...the 2 values are significantly different.
