thank you very much

You usualiy sh at three different spots on a lake. Your father beiieves the total daily weight of sh one can catch is no different across the three different spots. To test his claim you record the weight of sh you caught in a period of 13 days with 6 days spent on each spot. You obtain the following sample data from your shing experience: SUMMARY Groups Count Sum Average Variance Spot 1 6 100.5 16.75 1.75 Spot 2 6 100.5 16.75 1.35 Spot 3 6 102 17 3.2 What is die value of the mean square of errors? Select one: 0 a. 0.25 O b. 64.0 0 c. 2.1 0 d. 0.5 0 e. 31.6 \fSuppose we have made an intervai estimation for the mean of the population such as: [456, 5,671. If we realize that the true population mean is 6.01, what should be conclude? Select one: 0 a We should rst standardize the LCL and UCL and then see of they capture the mean 0 b. We could never get this result 0 c. We must use a tdistribution instead of a 2 distribution 0 d. The procedure can still be valid, since we allow for a certain amount of error 0 e. The procedure for interval estimation must have been done incorrectly
