Based on the data collected. the researchers computed a 96 percent condence interval for the true difference between the proportions of adult females minus the proportion of adult males who use 2 or more creditfdebit cards. The condence interval is: (0.013, 0.049). Assume a\" checks have been veried.

O We are 96% confident that the true proportion of females who use 2 or more credit/debit cards is less than the true proportion of males who use 2 or more credit/debit cards. O We are 96% confident that there is no statistically significant difference between the true proportion of females who use 2 or more credit/debit cards and the true proportion of males who use 2 or more credit/debit cards.
