Suppose we want to know whether the mean length of unemployment differs among the residents of two local communities. Sample information is as follows: Community A: sample mean = 3.4 months s = 1.1 month n = 52 Community B: sample mean = 2.8 months S = 0.8 month n = 62 Set up the null and alternative hypotheses. Use a = 0.05. Choose a particular test, and show the rejection regions on a diagram. Calculate the test statistic, and decide whether to reject the null hypothesis. (Do not assume that the two standard deviation are equal to one another – therefore a pooled estimate of s should not be found.)

community A: sample mean = 3.4 months
%3D
S = 1.1 month
n = 52
Community B: sample mean = 2.8 months
s = 0.8 month
n = 62
Set up the null and alternative hypotheses. Use a = 0.05. Choose a particular test,
and show the rejection regions on a diagram. Calculate the test statistic, and decide
whether to reject the null hypothesis. (Do not assume that the two standard deviations
are equal to one another – therefore a pooled estimate of s should not be found.)
