A regional opera company has tried two different appproaches for soliciting donations form 16 potential sponsors. The 16 potential sponsors were selected at random from a population of potential sponsors and randomly divided into two groups of eight each. Then one of the approaches was used for each group. Assume the population variances are not equal here. The dollar amounts of the resulting contributions are as follows: Approach 1 $1000 $1500 $1200 $1800 $1600 $1100 $1000 $1250 Approach 2 $1500 $1000 $1200 $1500 $1200 $1250 $1100 $1000 Is there any evidencee to indicate that the two approaches differ with respect to the mean amount donated?

Question
A regional opera company has tried two different appproaches for soliciting donations form 16 potential sponsors. The 16 potential sponsors were selected at random from a population of potential sponsors and randomly divided into two groups of eight each. Then one of the approaches was used for each group. Assume the population variances are not equal here. The dollar amounts of the resulting contributions are as follows:
| Approach 1 | $1000 | $1500 | $1200 | $1800 | $1600 | $1100 | $1000 | $1250 |
| Approach 2 | $1500 | $1000 | $1200 | $1500 | $1200 | $1250 | $1100 | $1000 |
Is there any evidencee to indicate that the two approaches differ with respect to the mean amount donated?
