Puas yog hlau nplaum cuam tshuam rau kev loj hlob ntawm cov nroj tsuag science ncaj ncees project?
Hypothesis: Cov hlau nplaum yuav ua rau kom cov nroj tsuag loj hlob vim yog cov hlau nplaum emissions. Alternative Hypothesis: Cov hlau nplaum yuav txo qhov kev loj hlob ntawm cov nroj tsuag vim yog cov hlau nplaum emissions. Null Hypothesis: Cov hlau nplaum yuav tsis cuam tshuam cov nroj tsuag kev loj hlob txhua
Puas yog cov neeg caij dav hlau thiab cov kws tsav dav hlau sib txuas?
Tsis yog cov kws tsav dav hlau sib txuas nrog cov neeg caij tsheb nkaus xwb tab sis kuj tseem muaj cov neeg caij tsheb sib ntsib, cov poj niam random ntawm cov tsev so tuav thiab lwm yam. Ib yam mus rau cov neeg tuaj koom hauv davhlau, ntau tus neeg uas muaj ntau tus txiv neej lawv pom nyob rau hauv ntau qhov chaw.
