Researchers measured the weight(g) of 25 randomly selected bubblefish from a population living in an isolated pond. They were trying to determine if the individuals in this population of bubblefish are growing significantly heavier than the typical bubblefish which are known to weigh 83.0g on average. Mean (Xbar) 85.0 4.0 25 Conduct an appropriate hypothesis test to answer the researchers' question and provide the answers below. The test-statistic (t) for this test is 4.86 . The p-value for this test is <.0005 . The results of the test confirm that the isolated bubble fish are lighter than the typical bubblefish. .
