What can be concluded at the or = 0.05 level of significance? a. For this study, we should use |Select an answer b. The null and alternative hypotheses would be: Ho: 7 v Select an answer V H1: 2 v Select an answer V C. The test statistic ? = (please show your answer to 3 decimal places.) d. The p-value = (Please show your answer to 4 decimal places.) e. The p-value is ? va f. Based on this, we should Select an answer | the null hypothesis. e. Thus, the final conclusion is that ... The data suggest the population mean is not significantly less than 5 at or = 0.05, so there is sufficient evidence to conclude that the population mean number of cavities for twenty-year olds is equal to 5. The data suggest that the population mean number of cavities for twenty-year-olds is not significantly less than 5 at a = 0.05, so there is insufficient evidence to conclude that the population mean number of cavities for twenty-year-olds is less than 5. O The data suggest the populaton mean is significantly less than 5 at o = 0.05, so there is sufficient evidence to conclude that the population mean number of cavities for twenty-year- olds is less than 5. h. Interpret the p-value in the context of the study. If the population mean number of cavities for twenty-year-olds is 5 and if you survey another 13 twenty-year-olds, then there would be a 20.77841182% chance that the sample mean for these 13 twenty-year-olds would be less than 4.69. There is a 20.77841182% chance of a Type | error. There is a 20.77841182% chance that the population mean number of cavities for twenty-year- olds is less than 5. Olf the population mean number of cavities for twenty-year-olds is 5 and if you survey another 13 twenty-year-olds, then there would be a 20.77841182% chance that the population mean number of cavities for twenty-year-olds would be less than 5. i. Interpret the level of significance in the context of the study. If the population mean number of cavities for twenty-year-olds is less than 5 and if you survey another 13 twenty-year-olds, then there would be a 5% chance that we would end up falsely concuding that the population mean number of cavities for twenty-year-olds is equal to 5. There is a 5% chance that flossing will take care of the problem, so this study is not necessary. If the population mean number of cavities for twenty-year olds is 5 and if you survey another 13 twenty-year-olds, then there would be a 5% chance that we would end up falsely concuding that the population mean number of cavities for twenty-year olds is less than 5
