The sample mean is a good estimate for the population mean.
The point estimate is a single value that is used to estimate an unknown population parameter based on a sample. In this case, we are trying to estimate the population mean weight of rainbow trout fingerlings in the pond based on a sample of 40 trout.
The given information tells us that the sample mean weight is 402.7 grams and the sample standard deviation is 8.8 grams.
Since we are estimating the population mean, the point estimate would be the sample mean. Therefore, the point estimate is 402.7 grams, which is option E.
