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? (i) i am 95% confident that this interval includes the sample mean (μ) arm length. (ii) i am confident that 95% of all planet x residents will have an arm length within this interval. (iii) i am confident that 95% planet x residents will have arm lengths within this interval. (iv) i am 95% confident that this interval includes the population mean arm length.
