1. Yes. There was difference in mean values of ducklings hatched among the five lakes.

2. All the five lakes, Swan, Loon, Minn, Eagle and Middle exhibit different in mean number of ducklings hatched.

The mean values of ducklings hatched can be obtained from the data in table 1.

Swan lake: 10+26+18+13+ 17+23+15+19 = 141/8 = 17.625

Loon lake = 12+10+4+16+6+5+6 = 59/7 = 8.42

Minn lake = 21+23+24+19+ 20+25+28+22+19 = 201/9 = 22.33

Eagle lake = 7+7+8+6+8+9+7+7+8 = 67/9 = 7.444

Middle lake = 5+6+7+5+4+5+3 = 35/7 =5
