A biologist needs to estimate the weight of all spiny lobsters on the Treasure Coast. To achieve this, the biologist collects a random sample of 20 spiny lobsters. The weights of each lobster in the sample are given below. Assume that the weights of all spiny lobsters on the Treasure Coast are normally distributed. 6.1 5.9 7 9 9.7 8.1 7.7 8 6.3 7.8 6.2 7.4 8.5 7.1 6.8 6.6 5.1 5.7 6.2 5.3 Determine the point estimate, and the sample standard deviation, s. Round the solutions to four decimal places, if necessary. H= Using a 95% confidence level, determine the margin of error, E, and a confidence interval for the average weight of a spiny lobster on the Treasure Coast. Report the confidence interval using interval notation. Round solutions to two decimal places, if necessary. The margin of error is given by E= A 95% confidence interval is given by
