  1. (a)In a random sample of 400 homeowners in a given locale, 168 indicate they heat their homes using OIL. The OIL HEATING Association (OHA) believes that 47% of the homes in that locale are heated by oil. BUT, the sample data suggests the claimed OHA proportion is OVERSTATED. Using a 2.5% level of significance, test the hypothesis that FEWER THAN 47% of the homes in that locale use OIL heat for their homes. SHOW SIX TYPICAL STEPS in a HYPOTHESIS TESTING analysis!

(b)please determine the P-value for this test.

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...
