If ī = 14.9, µ= 10.5, s= 10.3, n= 8, then t= .В. 1.202А. 1.30C. 1.21D. 1.226. The level of significance (usually .05) associated with a significance test is theprobability,A. That the alternative hypothesis is true.B. That the null hypothesis is true.C. Of not rejecting a true null hypothesis.D. Of rejecting a true null hypothesis. 7. The value set for a is known as:A. the rejection levelB. the acceptance levelC. the significance levelD. the error in the hypothesis test8. If a researcher takes a large enough sample, he/she will almost always obtain:A. virtually significant resultsB. practically significant resultsC. consequentially significant resultsD. statistically significant results9. One-tailed alternatives are phrased in terms of:B. < or >A. +C. + or =D. s or 210. A two-tailed test is one where:A. results in only one direction can lead to rejection of the null hypothesisB. negative sample means lead to rejection of the null hypothesisC. results in either of two directions can lead to rejection of the null hypothesisD. no results lead to the rejection of the null hypothesis
