Reliаnce оn sоlid biоmаss fuel for cooking аnd heating exposes many children from developing countries to high levels of indoor air pollution. The article “Domestic Fuels, Indoor Air Pollution, and Children’s Health” (Annals of the N.Y. Academy of Sciences, 2008: 209–217) presented information on various pulmonary characteristics in samples of children whose households in India used either biomass fuel or liquefied petroleum gas (LPG). For 75 children in biomass households, the sample mean peak expiratory flow (a person’s maximum speed of expiration) was 3.30 L/s, and the sample standard deviation was 1.20. For the 78 children whose households used liquefied petroleum gas, the sample mean PEF was 4.25 and the sample standard deviation was 1.75. Estimate the difference in PEF between children living in households using biomass fuel and liquified petroleum gas using a 90% confidence level. Do we have reason to believe that children who live in households that use biomass fuel have lower PEF than children from LPG households?
