Most communication developers claim that a 5G+ wireless connection would give an averagespectral efficiency of exactly 30 bps/Hz. To test the claim, a spectral efficiency performancefrom a random sample of MIMO technologies in bps/Hz has been obtained below:30.529.630.230.62931.629.131.630.930.930.729.229.230.830.630.330.53029.830.932.730.330.33030.831.730.62932.529.829.331.930.930.329.3Using the sample data above, show and compute the point estimate of the true average spectralefficiency. Next, test whether the claim is true at the 98.5% confidence level. Finally, repeat thetest using the p-value approach at the 98.5% confidence level.

To compare the dry braking distances from 30 to 0 miles per hour for two makes of automobiles, a safety engineer conducts braking tests for 35 models of Make A and 35 models of Make B. The mean braking distance for Make A is 43 feet. Assume the population standard deviation is 4.6 feet. The mean braking distance for Make B is 46 feet. Assume the population standard deviation is 4.5 feet. At α=0.10, can the engineer support the claim that the mean braking distances are different for the two makes of automobiles? Assume the samples are random and independent, and the populations are normally distributed. The critical value(s) is/are Find the standardized test statistic z for μ1−μ2.

Over the past 10 years, contestants at the county fair hotdog eating contest averaged 125 hotdogs within the 1 minute time frame. Due to Covid19 restrictions, there were only 15 contestants who ate an average of 122 hotdogs. s=6.5 We're interested in finding out if there is significant change in hotdog eating. Use the hypothesis that H0: µ=125, Ha: #125. What is the SE? 10.9 1.7 6.5 8.3

10.53 A study was conducted at Virginia Tech to de- termine if the "strength" of a wound from surgical inci- sion is affected by the temperature of the knife. Eight dogs were used in the experiment. "Hot" and "cold" incisions were made on the abdomen of each dog, and the strength was measured. The resulting data appear below.

Question 4 The Department of Energy wants to determine the percentage of mining firms that follow energy saving production processes. A random sample of 250 mining firms was selected and it was found that 95 out of 250 firms follow these practices. Estimate with 99% confidence, the percentage interval of mining firms that practice the energy saving production processes. Use a critical value of 2,58.
