Question

A biologist has taken a random sample of a specific type of fish from a large lake to check for levels of mercury. A 95 percent confidence interval was calculated to be 6.8 ±1.2 pounds. Which of the following is true? a. 95 percent of all the fish in the lake weigh between 5.6 and 8 pounds b.In repeated sampling, 95 percent of the sample proportions will fall within 5.6 and 8 pounds c.In repeated sampling, 95% of the time the true population mean of fish weights will be equal to 6.8 pounds d.In repeated sampling, 95% of the time the true population mean of fish weight will be captured in the constructed interval e.We are 95 percent confident that all the fish weigh less than 8 pounds in this lake

Explanation / Answer
