Use technology to perform two-sample t-test to determine whether there is a difference in the mint dates and in the values of the coins found on a street from 1985 through 1996 for the two mint locations. Use a=0.05 (A). Mint dates of coins(years) Philadelphia: x-bar 1=1984.8, s1=8.6 n1=7133. Denver: x-bar2=1983.4, s2=8.4, n2=4726. Assume population variances are equal. (B). Value of coins(dollars) Philadelphia: x-bar1=$0.034, s1=$0.054, n1=7133. Denver: x-bar2=$0.033, s2=$0.052, n2=4726. Assume population varances are not equal.

A drug treatment can sometimes be affected by the use of another drug taken concomitantly. This is why doctors and pharmacists routinely ask patients about all the drugs they use, even the ones available over the counter. One study examined the impact of nonsteroidal anti-inflammatory drugs (NSAIDs) on the efficacy of the antidepressant citalopram in clinically depressed individuals. Data from a large clinical trial were reviewed, and clinical remission from depressive symptoms was assessed for individuals who had taken NSAIDs concomitantly and those who had not. The findings are given in the table. NSAID use No NSAID use Remission 182 628 No remission 227 509 How strong is the evidence that concomitant NSAID use lowers the effectiveness of the antidepressant citalopram? Follow the four-step process.
