Q:

Assume that the following confidence interval for the difference in the mean length of male​ (sample 1) and female babies​ (sample 2) at birth was constructed using independent simple random samples. What does the confidence interval suggest about the difference in length between male babies and female​ babies? minus −0.2 in. less than < mu 1 μ1 minus − mu 2 μ2 less than <1.7 in.a female babies are longerb male babies are longerc there is no difference in the length between male and female babies

Accepted Solution

A:
Answer:The example stated indicate that there is no difference in the means of the two samplesStep-by-step explanation:SolutionRecall thatThe Confidence interval in the mean length of male (sample 1) and female sample (2) babies,which is,Male babies= sample 1Female babies = sample 2What is the difference in length between male and female babies as suggested by the Confidence intervalNow,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
