The computer science department is making a new recruitment poster for computer science majors and would like to include information about the average salary of a software developer on the Treasure Coast. To estimate the average salary of a software developer, someone from the department collected a random sample of 10 local software developers. Their salaries are listed below. Assume that the salaries of all software developers on the Treasure Coast are normally distributed. 81,752 81,660 82,818 82,277 82,268 82,704 81,591 81,374 81,551 81,715 Determine the point estimate, and the sample standard deviation, 8. Round the solutions to four decimal places, if necessary 2 = Using a 99% confidence level, determine the margin of error, E, and a confidence interval for the average salary of a software developer 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 99% confidence interval is given by

A normal resting heart rate for adults ranges from about 60 to 100 beats per minute (BPM). A doctor would like to estimate the average heart rate for one of her patients. The doctor instructs her patient to measure their resting heart rate twice a day for one week. The measurements are listed below. Assume that the distribution of all heart rate measurements of this patient is approximately normally distributed. 100 95 103 95 99 100 99 104 96 91 96 104 93 102 Determine the point estimate, and the sample standard deviation, s. Round the solutions to four decimal places, if necessary. = 8 Using a 98% confidence level, determine the margin of error, E, and a confidence interval for the average resting heart rate of this patient. Report the confidence interval using interval notation. Round solutions to two decimal places, if necessary. The margin of error is given by E = A 98% confidence interval is given by

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. 9.9 6 9.2 8.3 5.2 9.5 6.7 9.4 9.5 6 8.5 5.9 6.7 8.8 5.3 7.5 7.1 7.3 8.5 9.2 Determine the point estimate, and the sample standard deviation, s. Round the solutions to four decimal places, if necessary. Using an 80% 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 = An 80% confidence interval is given by
