<prompt> Sepheo sa khopolo-taba e se nang thuso tekong ea lipalo ke efe?nan  <response>: Instruction in English: What is the purpose of a null hypothesis in a statistical test? . Response in English: The null hypothesis is an essential component of statistical hypothesis testing, a method used to determine whether there is sufficient evidence to infer that a relationship exists between variables. The null hypothesis represents the default assumption, which is typically that there is no relationship between the variables in question, and any observed effects are due to chance. The purpose of the null hypothesis is to provide a benchmark against which the alternative hypothesis, which represents the research question, can be tested. By comparing the data with the null hypothesis, it is possible to determine whether the results are statistically significant or if they could have occurred by chance. If the data provides strong evidence against the null hypothesis, it can be rejected, providing support for the alternative hypothesis. This process allows researchers to make inferences about populations based on the data from a sample, and helps to ensure the validity and reliability of the results. . Response in Sesotho: The null hypothesis ke karolo ea bohlokoa ea tlhahlobo ea lipalo-palo, mokhoa o sebelisoang ho fumana hore na ho na le bopaki bo lekaneng ba ho fana ka maikutlo a hore kamano e teng lipakeng tsa mefuta-futa. Khopolo-taba e se nang thuso e emela monahano o sa feleng, oo hangata e leng hore ha ho na kamano pakeng tsa mefuta-futa eo ho buuoang ka eona, me liphello leha e le life tse hlokometsoeng li bakoa ke tsietsi. Sepheo sa khopolo-taba e se nang thuso ke ho fana ka tekanyo eo khopolo e ngoe, e emelang potso ea lipatlisiso, e ka lekoang khahlanong le eona. Ka ho bapisa lintlha le khopolo-taba e se nang thuso, hoa khoneha ho fumana hore na liphello ke tsa bohlokoa kapa li ka etsahala ka tšohanyetso. Haeba data e fana ka bopaki bo matla khahlanong le khopolo-taba e se nang thuso, e ka haneloa, e fana ka tšehetso bakeng sa khopolo e ngoe. Tsebetso ena e lumella bafuputsi ho etsa liqeto mabapi le palo ea batho ho latela lintlha tse tsoang sampoleng, me e thusa ho netefatsa bonnete le tsepahalo ea liphetho.
