# Question: Use the following sample information to construct a 90 confidence

Use the following sample information to construct a 90% confidence interval for the difference in the two population means.

Sample 1 ... Sample 2

n1 = 32 ..... n2 = 31

xÌ„1 = 70.4 ... xÌ„2 = 68.7

Ïƒ21 = 5.76 .... Ïƒ22 = 6.1

Sample 1 ... Sample 2

n1 = 32 ..... n2 = 31

xÌ„1 = 70.4 ... xÌ„2 = 68.7

Ïƒ21 = 5.76 .... Ïƒ22 = 6.1
