Hypothesis Tests A study was conducted to determine if the salaries of elementary school teachers from two neighboring districts were different. A sample of teachers from each district was randomly selected. Test the claim that the salaries from both districts are not equal. Assume the samples are random, independent and populations are normally distributed. Also, assume that they have unequal variances. Use = 0.06. (Round to four decimals) Ho: _________________________ Ha: _________________________ =______________ Which hypothesis represents the claim? Circle: Null Hypothesis or Alternative Hypothesis District 1 District 2 1 = $39,810 2 = $26,850 1 = $1053 2 = $2290 1 = 22 2 = 28 Find the critical values of the rejection region. (Show calculator function used, values plugged into calculator function, and final answer rounded to 4 decimals. Sketch the rejection region on the normal curve.) Test this hypothesis. (Show original formula, values then plugged into formula, and final answer rounded to 4 decimals) Decision (Reject or Fail to Reject): ___________________ Write a conclusion in context of this problem. At ___% level of significance, there ____________ enough evidence to _____________ the claim that _______________________________________________________________________________________ ______________________________________________________________________________________.
