1. An oven chimney is made of brick with a heat transmission coefficient 1.1 W/mK 10 cm thick. Since the shaft exterior radiation beam coefficient is 0.8 and the flue gas temperature is 350°C, the external ambient temperature is 25°C and the outer ambient heat transport coefficient is 20 W/m2K; a) Calculate the shaft exterior temperature. b) In order to reduce the risk of burn injury that may occur in the body, the shaft is asked to be below 55°Cve...

1 Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test the hypothesis that the proportion of one-person households exceeds 0.27. A random sample of 125 households found that 43 consisted of one person. The Census Bureau would like to set α = 0.05. Use the critical value approach to test this hypothesis. Explain. 2 Organizations are relying more and more on social-networking sites to research job candidates. According to...

1. Previous research states, "no evidence currently exists supporting or refuting the use of electric fans during heat waves" in terms of mortality and illness. Counterintuitively, Public Health guidelines suggest not using fans during hot weather, with some research reporting the potential of fans accelerating body heating. You decide to research further this seemingly contradictory guidance, hypothesizing that the true population average core body temperature amidst higher ambient temperature and humidity levels while using an electric fan is greater than...

1. A city official claims that the proportion of all commuters who are in favor of an expanded public transportation system is 50%. A newspaper conducts a survey to determine whether this proportion is different from 50%. Out of 225 randomly chosen commuters, the survey finds that 90 of them reply yes when asked if they support an expanded public transportation system. Test the official’s claim at α = 0.05. 2. A survey of 225 randomly chosen commuters are asked...
