Question 2>The average number of cavities that thirty-year-old Americans have had in their lifetimes is 7. Do twenty-year-olds have a different number of cavities? The data show the results of a survey of 14 twenty-year-oldswho were asked how many cavities they have had. Assume that the distribution of the population isnormal.7, 8, 7, 7, 9, 7, 10, 9, 8, 10, 6, 9, 6, 8What can be concluded at the a = 0.05 level of significance?%3Da. For this study, we should use Select an answerb. The null and alternative hypotheses would be:Но: |?Select an answerH1:Select an answer vc. The test statistic ? v =(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 ? vaf. Based on this, we should Select an answer v the null hypothesis.g. Thus, the final conclusion is that .The data suggest the populaton mean is significantly different from 7 at a = 0.05, so there issufficient evidence to conclude that the population mean number of cavities for twenty-year-olds is different from 7.O The data suggest that the population mean number of cavities for twenty-year-olds is notsignificantly different from 7 at a = 0.05, so there is insufficient evidence to conclude thatthe population mean number of cavities for twenty-year-olds is different from 7.%3DThe data suggest the population mean is not significantly different from 7 at a = 0.05, sothere is sufficient evidence to conclude that the population mean number of cavities fortwenty-year-olds is equal to 7.%3Dh. Interpret the p-value in the context of the study. h. Interpret the p-value in the context of the study.There is a 2.1341638% chance of a Type I error.O If the population mean number of cavities for twenty-year-olds is 7 and if you survey another14 twenty-year-olds then there would be a 2.1341638% chance that the population mean wouldeither be less than 6.07 or greater than 8.O There is a 2.1341638% chance that the population mean number of cavities for twenty-year-olds is not equal to 7.O If the population mean number of cavities for twenty-year-olds is 7 and if you survey another14 twenty-year-olds, then there would be a 2.1341638% chance that the sample mean for these14 twenty-year-olds would either be less than 6.07 or greater than 8.i. Interpret the level of significance in the context of the study.O If the population mean number of cavities for twenty-year-olds is different from 7 and if yousurvey another 14 twenty-year-olds, then there would be a 5% chance that we would end upfalsely concuding that the population mean number of cavities for twenty-year-olds is equal to7.O There is a 5% chance that the population mean number of cavities for twenty-year-olds isdifferent from 7.There is a 5% chance that flossing will take care of the problem, so this study is not necessary.O If the population mean number of cavities for twenty-year-olds is 7 and if you survey another14 twenty-year-olds, then there would be a 5% chance that we would end up falsely concudingthat the population mean number of cavities for twenty-year-olds is different from 7.
