The two intervals (114.8, 115.4) and (114.5, 115.7) are confidence intervals (computed using the same sample data) for μ = true average resonance frequency (in hertz) for all tennis rackets of a certain type. (a) what is the value of the sample mean resonance frequency? (hint: where is the confidence interval ) both intervals were calculated from the same sample data. the confidence level for one interval is 90%; the confidence level for the other interval is 99%. which interval is the 90% confidence level, and why?
