Assume that the following confidence interval for the difference in the mean length of male babies (sample 1) and female babies (sample 2) at birth was constructed using independent simple random samples:0.2 in2.7 in. What does the confidence interval suggest about the difference in length between male babies and female babies?

The confidence interval consist of positive values, it implies that the mean length of male babies at birth is more than that of female babies.

Step-by-step explanation:

Consider the hypothesis for testing the difference in the mean length of male babies and female babies at birth:

H₀: There is no significant difference between the mean length of male babies and female babies at birth, i.e. μ₁ - μ₂ = 0.

Hₐ: There is a significant difference between the mean length of male babies and female babies at birth, i.e. μ₁ - μ₂ ≠ 0.

The decision rule based on the confidence interval is:

If the (1 - α)% confidence interval does not consist of the null value, i.e. 0 then the null hypothesis will be rejected.

The confidence interval for the difference in the mean length of male babies and female babies at birth is:

CI = (0.2 in, 2.7 in)

The confidence interval does not consist of the null value, i.e. 0.

Thus, the null hypothesis will be rejected.

Hence, concluding that there is a significant difference between the mean length of male babies and female babies at birth.

Since the confidence interval consist of positive values, it implies that the mean length of male babies at birth is more than that of female babies.
