uestion 16 of 22 In Incorrect Ma Sapling Learning 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 ablated. Are the masses of the Canadian and U.S. one-cent coins significantly different at the 98% confidence level? The table of Student's t values can be found here. Assume that the population standard deviation (a) for each data set is the same. Masses of individual pennies O The difference is significant. The difference is not significant.

Calculate the t value to compare these two data sets. For these sets of measurements the 98% confidence level? 2.547 2.526 2.539 2512ed4296 Number O The difference is significant.
