Each of the following is a confidence interval for $\mu=$ true average (i.e., population mean) resonance frequency(Hz) for all tennis rackets of a certain type:(114.4,115.6)$\quad(114.1,115.9)$What is the value of the sample mean resonance frequency?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?

The following table provides the Noradrenaline concentration (µmol/g of creatinine) obtained by analyzing the urine of healthy volunteers between twenty and thirty years of age. Male 0,48 0,36 0,20 0,55 0,45 0,46 0,47 0,23 Female 0,35 0,37 0,27 0,29 Can noradrenaline concentrations be considered to be significantly different between the sexes (considering the 95% confidence level)? Carry out the appropriate hypothesis test, clearly showing how the calculated, critical values (confidence level and degrees of freedom) were obtained and concluding in full whether the null hypothesis is true or not.
