Question Dalton is a public school teacher in Burlington. After a conversation with a colleague in Sudbury, Dalton realizes that his salary is much lower than his colleague's, even though they have similar backgrounds and work experiences. Dalton theorizes that the population mean annual salary for a public school teacher in Burlington is lower than the population mean annual salary for a public school teacher in Sudbury. He conducts research on the inquiry and assumes that the population standard deviation is $2,409 for Burlington and $3,192 for Sudbury. Dalton randomly selects the salaries of public school teachers in Burlington and in Sudbury. The results of Dalton's findings are shown in the table below. Let 1 be the population mean annual salary for a public school teacher in Burlington and H2 be the population mean annual salary for a public school teacher in Sudbury. What type of test is this hypothesis test? Burlington Sudbury X $54,906 X2 = $56,561 n1= 36 n2 = 33 Select the correct answer below: Select the correct answer below: This is a left-tailed test because the alternative hypothesis is Ha: -A2 < O This is a left-tailed test because the alternative hypothesis is Ha : 41-2> 0 This is a right-tailed test because the alternative hypothesis is H4: -2 > 0 This is a right-tailed test because the alternative hypothesis is H: - < 0 This is a two-tailed test because the alternative hypothesis is Ha: ,- 42 0.
