Construct the indicated confidence interval for the population mean u using the t-distribution. Assume the population is normally distributed. c= 0.90, x= 13.9, s=0.73, n= 19 夏 (国圓) (Round to one decimal place as needed.)

The two intervals (114.9, 115.7) and (114.6, 116.0) are confidence intervals (calculated using the same sample data) for ? = 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%?   (114.9, 115.7) (114.6, 116.0)     It is impossible to tell which is which.   How can you tell? The 99% confidence interval should be wider than the 90% confidence interval.   The center of the 99% confidence interval should be greater than the center of the 90% confidence interval.       The 99% confidence interval should be narrower than the 90% confidence interval.   The center of the 99% confidence interval should be less than the center of the 90% confidence interval.   It is impossible to tell which…
