Question

A broker believes that the average price of two bonds (Bond A and Bond B) are equal.  The broker does not know the population standard deviation of the two securities.  The following information outlines the information for each sample:

Stock A                                  Stock B

n1=8                                      n2=13

X1=$86                                  X2=$94

s1=$4                                    s2=$12

If you count on the population variances not being equal.  Test the broker's claim at the .01 level.  Also, test to see whether the population variances are equal or not equal at the 0.05 level.
