An engineer wishes to estimate a population mean . Assume independent and identically distributed observations, a known population standard deviation of , and that the sampling distribution of the sample mean is well approximated by a Gaussian distribution. What is the minimum sample size required to estimate with 95% confidence and a maximum margin of error of ?

Repeated voltage measurements from a sensor are assumed to be independent and identically distributed, with known population standard deviation mV. An engineer averages measurements. What is the standard error of the sample mean? Give your answer in mV. (You only need to provide a numerical value. You do not need to enter the units.)

Continuing with the wireless sensor network scenario introduced in Questions 1 to 3, suppose the -score corresponding to an observed sample packet-loss rate is . Using a -table, estimate the probability that the sample packet-loss rate is less than or equal to the aforementioned observed sample packet-loss rate. (Input your answer as a decimal rather than a fraction, and include at least 2 decimal places.)

Continuing with the wireless sensor network scenario introduced in Questions 1 and 2, suppose the packet-loss probability is . A test transmits packets. Using the Central Limit Theorem, the sample packet-loss rate may be approximated as Gaussian. What is the -score corresponding to an observed sample packet-loss rate of 0.08? (Input your answer as a decimal rather than a fraction, and include at least 2 decimal places.)
