In relation to the Sustainable Development Goals of the United Nations, one of the critical measures being monitored by the World Health Organization is the annual mean concentrations of fine particulate matter of less than 2.5 microns of diameter (or PM2.5, in ug/m3 units] in urban areas. This is the usual indicator of air pollution. As of 2016, the World Health Organization reported that urban areas in the US have an average of 7.55 ug/m3. You believe that this might have declined in the country due to suspension of economic activities (like transportation operations) during the COVID-19 pandemic. Let us assume the variable follows a normal distribution with standard deviation of 0.11 ug/m3. From the 75 US urban areas that are randomly sampled, the mean is found to be 7.51 ug/m3 (for this same PM2.5 concentration). Conduct a hypothesis test at 5% level of significance.

Radon is a gas emitted from the ground that can collect in houses in buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable” Radon levels in a house vary from week to week. In one house, a sample of 6 weeks had the following readings for radon level (in pCi/L): 1.9 2.8 3.9 3.9 4.2 5.7 Find the variance and standard deviation (definitional formula).

The National Institute of Standards and Technology (NIST) offers a wide variety of “standard reference materials” (SRMs) with accurately specified analyte concentrations. SRM 1951c is intended in part for “evaluating the accuracy of clinical procedures for the determination of total cholesterol . . . in human serum.” The certified total cholesterol is 6.244 ± 0.072 mmol/L. For the sake of this question, let’s treat 6.244 mmol/L as its “true” value (μ). We will use this standard to test a method with an intrinsic variability (for an experienced analyst) of σ = 0.131 mmol/L. 1. For what value of z does exactly 95% of the area under a Gaussian curve lie between ± z? Use this multiplier to find the range of measured cholesterol concentrations that would include 95% of the trials from the “parent population” (μ and σ) given above. 2. Calculate z for a trial in which the measured total cholesterol concentration is 6.302 mmol/L. 3. What is the probability that a trial will give a cholesterol…
