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.

An experiment was performed to determine whether different types of chocolate take different amounts of time to dissolve. Forty people were divided into five groups. Each group was assigned a certain type of chocolate. Each person dissolved one piece of chocolate, and the dissolve time (in seconds) was recorded. For comparison, each person in each group also dissolved one piece of butterscotch candy; these pieces were identical for all groups. The data, which include the group, the dissolve times for both chocolate and butterscotch, the difference between the dissolve times, and the ratio of the dissolve times, are presented in the following table. Note that the design is slightly unbalanced; group 3 has nine people and group 5 has only seven.
