Assume you are interested in the thermal conductivity for a specific iron at 100°F and 550W. You collect 45 samples and calculate the mean, x = 41.924 Btu/hr-ft-°F. Assume you know the population standard deviation for this specific iron, and conditions is σ = 0.30 Btu/hr-ft-°F. Construct a 95% confidence level around the true population mean for thermal conductivity.

    Suppose you are interested in finding out how happy the students are at UNR. You design a survey that probes aspects of an individual’s emotional life, and using this survey are able to compute an accuracy index score ranging from 0 (completely miserable) to 100 (nauseatingly happy). You know that the standard deviation of the population (sigma) equals 8; however you do not know, and want to know, what the mean of the population (mu) is. Rather than give the...
