Question
The two intervals (114.7, 115.7) and (114.4, 116.0) are confidence intervals (calculated using the same sample data) for u = true average resonance frequency (in hertz) for all tennis rackets of a certain type.
(a) What is the value (in hertz) of the sample mean resonance frequency? (Hint: Where is the confidence interval centered?)
hertz
(b) The confidence level for one of these intervals is 90% and for the other it is 99%. Which one has a confidence level of 99%?
O (114.7, 115.7)
O (114.4, 116.0)
O It is impossible to tell which is which.
How can you tell?
O The 99% confidence interval should be narrower than the 90% confidence interval.
O The center of the 99% confidence interval should be less than the center of the 90% confidence interval.
O The center of the 99% confidence interval should be greater than the center of the 90% confidence interval.
O The 99% confidence interval should be wider than the 90% confidence interval.
O It is impossible to tell which is which.
