Justin and Hayley conducted a mission to a new planet, Planet X, to study arm length. They took a random sample of 100 Planet X residents. Then they calculated a 95% confidence interval for the mean arm length. What does a 95% confidence interval for arm length tell us in this case? Group of answer choices I am 95% confident that this interval includes the sample mean ( ) arm length. I am confident that 95% of all Planet X residents will have an arm length within this interval. I am confident that 95% of the 100 Planet X residents surveyed will have arm lengths within this interval. I am 95% confident that this interval includes the population mean arm length.
