Answer:

The example stated indicate that there is no difference in the means of the two samples

Step-by-step explanation:

Solution

Recall that

The Confidence interval in the mean length of male (sample 1) and female sample (2) babies,which is,

Male babies= sample 1

Female babies = sample 2

What is the difference in length between male and female babies as suggested by the Confidence interval

Now,

The calculated Confidence interval is given as:

-0.2 < mu1 - mu2 < 1.7

So,

0 is included in the above CI, this indicates or suggests that there is no difference in the means of the two samples
