Magnetic surveying is one technique used by archaeologists to determine anomalies arising from variations in magnetic susceptibility. Unusual changes in magnetic susceptibility might (or might not) indicate an important archaeological discovery. Let x be a random variable that represents a magnetic susceptibility (MS) reading for a randomly chosen site at an archaeological research location. A random sample of 120 sites gave the readings shown in the table below.

The heart rates before and after running a race (in beats per minute) of a sample of four athletes are shown in the following table: Athlete Heart rate before Heart rate after 120 129 134 123 50 52 3 56 4 53 The aim of the experiment was to determine whether the population mean heart rate after a race is more than 70 beats per minute greater than before the race. 1.4 Use the appropriate hypotheses test to determine whether the population mean heart rate after a race is more than 70 beats per minute greater than before the race. Use a = 0.05 and also find the approximate p-value. Also mention any assumptions made. Using your answer in 1.4), comment on whether you are subject to a Type I or a Type II error. Describe this error in the context of this problem. Estimate the difference in the mean heart rate by calculating a 90% confidence intervai for the data. Use this result to determine whether the population mean heart rate after a race is more than 70 beats per minute greater than…
