Female frogs from two different lakes were caught and released to determine the number of eggs they produce. One lake had cottages along the waterfront, the other did not. Does the data below provide strong evidence of a difference between the two lakes? (Use a two-sided test.) Assume that conditions for inference are satisfied. Lake with cottages: Mean=25.3, SD=8.2, number of frogs tested=20. Lakes with no cottages: Mean=30.4, SD=10.8, number of frogs tested: 25
