U.S. economy only hinders people more with high gas prices. A one population test using the One Factor ANOVA test and a five-step hypothesis test can be used to determine if gas prices are equally high in many different states. The samples used to test the hypothesis come from data collected from 30 randomly selected gas stations in six different cities. The hypothesis test and some solutions to consider may have an effect on direct and indirect stakeholders and is very important to the economy as

Alpha at .05 means there is a .05 probability or 5% chance of committing a Type I error‚ which means that we have rejected our null hypothesis and found support for our alternate hypothesis when‚ in fact‚ the null hypothesis was true. • What is your null hypothesis?

Sapir-Whorf Hypothesis ANT 101 July 19‚ 2013 The Sapir-Whorf Hypothesis theorizes that language is not just voicing something‚ but it is a shaper of ideas which basically means that language can determine our perceptions‚ thoughts‚ and behaviors in reality. Edward Sapir developed and published this hypothesis in the 1920’s. In 1956‚ Benjamin Lee Whorf published his work developing this hypothesis based on his work using the Hopi and English languages. Both of the ideas are commonly known

development of modern humans. The report discusses the most logical theories. In my view‚ the multi-region hypothesis is the most logical theory because it is better to prove facts of evolution. According to the multi-region hypothesis‚ the focus is on H. erectus‚ leaving Africa back and forth 2 million years back and developing into modern humanity. The focal point of the African hypothesis states that Homo sapiens originated through the evolution of H. erectus in Africa and then migrated to other

The hypothesis for the Oil Absorbency Lab was rejected. My hypothesis was that if a person puts a sponge in materials “crude oil”‚ then it will absorb the most amount of oil. The data collected from this experiment rejected the hypothesis because it stated that the sponge would absorb the most oil‚ but the sponge did not absorb more oil than the rag. The rag and sponge’s ranges were for the first trial was 53.0g‚ the second trial was 51.0g‚ and the third trial was 46.0g and the rag. The rag and
