5. For a random sample of 50 households with gas stoves monitored over a week, the sample mean CO2 level (ppm) in the households was -654.16, and the sample standard deviation was s 164.43. a. Check if the CLT (central limit theorem) applies and show the two assumptions that you check. b.

1.3.(4 points) A commercial kitchen is generally defined in British Standard (BS 6173) as a catering area that prepares meals for the public-in contrast to a primarily domestic setting such as a Bed & Breakfast. CO2 gas is a reliable indicator of the effectiveness of kitchen ventilation. IGEM/UP/19 states that for newly designed kitchens, the CO2 level in staff working areas should be less than 2,800 parts per million (ppm) and that the kitchen appliances - or their gas supplies-should...

The negative effects of ambient air pollution on children's lung function has been well established, but less research is available about the impact of indoor air pollution. The authors of an article investigated the relationship between indoor air-pollution metrics and lung function growth among children ages 6-13 years living in four Chinese cities. For each subject in the study, the authors measured an important lung-capacity index known as FEV1, the forced volume (in ml) of air that is exhaled in...

Question of 41 1.0 Points A 95% confidence interval for the true mean cholesterol level of adult males based on 25 randomly selected subjects extends from 175 mg 1 to 250 mg L. What is a proper interpretation of the confidence interval? A Ninety-five percent of the population has a cholesterol level between 175 and 250 m l B. We are 95% confident that the true mean cholesterol level of the population falls between 175 and 250 mgt C. More...
