Most communication developers claim that a 5G+ wireless connection would give an average spectral efficiency of exactly 30 bps/Hz. To test the claim, a spectral efficiency performance from a random sample of MIMO technologies in bps/Hz has been obtained below: 30.5 29.6 30.2 30.6 29 31.6 29.1 31.6 30.9 30.9 30.7 29.2 29.2 30.8 30.6 30.3 30.5 30 29.8 30.9 32.7 30.3 30.3 30 30.8 31.7 30.6 29 32.5 29.8 29.3 31.9 30.9 30.3 29.3 Using the sample data above, show and compute the point estimate of the true average spectral efficiency. Next, test whether the claim is true at the 98.5% confidence level. Finally, repeat the test using the p-value approach at the 98.5% confidence level.
