In an April 2009 study, it was reported that undergraduate students have a mean credit card balance of $3,125. This figure was at an all-time high and had increased 44% over the previous five years. A more current study was conducted using a sample size of 100 students and found that the mean credit card balance had increased further to $3,325. From previous studies, it is assumed that the population standard deviation is known to be o = 1,000. Suppose you want to test whether or not credit card balances have really increased relative to 2009 figures. In other words you want to test the following: Họ: H s $3,125 H: u > $3,125 Given the above information, what is the calculated p-value? O 0.0228 O 0.9500 O 0.0500 O 0.0456
