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
