Canadian (G) U.S. (G) 1 2.349 2.553 Although The Canadian And U.S. One-Cent Coins Have Slightly Different Dimensions And Alloy Compositions, The Two Types Of Pennies Have Similar Masses. The Table Below Lists The Masses Of Individual Pennies From Each Country Measured Using The Same Balance. Compare The Two Sets Of One-Cent Coins By Determining I Calculated.

The difference is significant The difference is not significant Suppose the number of replicate measurements and the average mass of an individual penny remain the same, but the standard deviation of each data set is three times greater than its original value. Calculate the railue to compare these two data sets, I calculated For the second set of measurements, is there a significant dillerence it the masses of the two types of coins at the For the second set of measurements, is there a significant difference in the masses of the two types of coins at the 98% conlidence level? The difference is significant. The difference is not significant.
