Each of the following is a confidence interval for= true average (i.e., population mean) resonance frequency (Hz) for all tennis rackets of a certain type:(114.4, 115.6)(114.1, 115.9)(a) What is the value of the sample mean resonance frequency?Hz(b) Both intervals were calculated from the same sample data. The confidence level for one of these intervals is 90% and for the other is 99%. Which of the intervals has the 90%confidence level, and why?O The first interval has the 90% confidence level because it is a narrower interval.The second interval has the 90% confidence level because it is a narrower interval.The first interval has the 90% confidence level because it is a wider interval.O The second interval has the 90% confidence level because it is a wider interval.
