Test the claim about the difference between two population means

1 and 2

at the level of significance

.

Assume the samples are random and independent, and the populations are normally distributed.

Claim:

1=2;

=0.01

Population parameters:

1=3.5,

2=1.7

Sample statistics:

x1=16,

n1=27,

x2=14,

n2=
