Te tātaitai wā o te whakaponotanga
Ka hanga he wā whakawhirinaki mō tētahi tauwaenga mai i te tauwaenga tauira, SD me te rahi.
Ka whakahōutia ngā hua i te wā e tātuhi ana.
Mo tēnei tātaitai
confidence interval is a measure of the probability of a sample to capture the true population mean. It is a measure of the probability of a sample to capture the true population mean. It is a measure of the probability of a sample to capture the true population mean. It is a measure of the probability of a sample to capture the true population mean. It is a measure of the probability of a sample to capture the true population mean. It is a measure of the probability of a sample to capture the true population mean. It is a measure of the probability of a sample to capture the true population mean.Work
Ko nga pātai e pā ana
He aha te tikanga o te wā whakaū 95%?
Ko te tikanga mēnā he maha ngā wā e whakawāteatia ai te tauira, ā, ka hangaia he wā i ia wā, tata ki te 95% o ēnei wā ka pupuri i te tauwāhi o te iwi whānui pono. Kāore te tikanga o tēnei he tūponotanga 95% o te tauwāhi i tēnei wā kotahi.
He aha te wā e whakamahia ai e au tētahi wā t?
Ka whakamahia te wā t ina iti te tauira (i raro iho i te 30) ā, kāore e mōhiotia te rerekētanga paerewa o te iwi whānui. He uaua ake te tuari t, e tuku ana i tētahi wā iti iho, nui ake te mātauranga i tēnei z-pūtake.
He aha te rohe o te hapa i roto i te wā o te whakapono?
Ko te roanga o te hapa te haurua o te whānui o te wā, z * · (σ / √n). Ka tāpiri atu rātau, ka tangohia rātau mai i te tauira hei whiwhi i ngā tepe o runga me te raro, nō reira ko te roanga iti iho te tikanga o tētahi matapae tika ake.
He pēhea te whakaiti i te wā o te whakaponotanga?
Kohikohi i tētahi tauira nui ake, mai i te whakaititanga o te whānui ki te pūtake tapawhā o n, te whakaae rānei ki tētahi taumata ātete iti iho. Ko te whakaiti i te tāupetanga i roto i tō tātou raraunga ka whakaiti hoki i te wā. Ko te whakawhāititanga o te rahi tauira e tata ana ki te haurua o te whānui.
Ka whakawhānui te taumata whakaponotanga tiketike ake i te wā?
He. Ko te hiahiatia he nui ake te whakaponotanga e whakamahi ana i tētahi uara hira nui ake z*, kia whānui ake ai te wā 99% i te wā 95% i hangaia mai i te raraunga ōrite. Kei te tīariari tonu te whakawhitinga i waenganui i te whakaponotanga me te tika.
He aha te hapa paerewa?
Ko te hapa paerewa te rerekētanga paerewa i wehea e te pūtake tapawhā o te rahi tauira (σ / √n). Ka ine i te nui o te tauira tauwāhi e rerekē ana i te tauira ki te tauira, ā, ko te pōhatu hanganga o te mārō hapa.
