A) D determine the point estimate, x and the sample standard deviation, s. Round the solution to four decimal places if necessary (the x has the line over top of it as seen in photo) x=s=B) using a 90% 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 the solution to two decimal places if necessary. The margin of error is given by E= A 90% confidence interval is given by

Question 22 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. 81,900 82,749 82, 122 81,573 81,439 81,653 82,939 81, 752 81,949 82,262 Determine the point estimate, T and the sample standard deviation, 8. Round the solutions to four decimal places, if necessary. T
