The average number of cavities that thirty-year-old Americans have had in their lifetimes is 5. Do twenty-year-olds have a different number of cavities? The data show the results of a survey of 11 twenty- year-olds who were asked how many cavities they have had. Assume that the distribution of the population is normal. 6, 5, 7, 4, 4, 7, 4, 6, 6, 5, 4 What can be concluded at the a - 0.01 level of significance? a. For this study, we should use Select an answer b. The null and alternative hypotheses would be: Họ: P v Select an answer H1: ? Select an answer c. 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 ? va f. Based on this, we should Select an answer v the null hypothesis. g. Thus, the final conclusion is that ... O The data suggest that the population mean number of cavities for twenty-year-olds is not significantly different from 5 at a = 0.01, so there is insufficient evidence to conclude that the population mean number of cavities for twenty-year-olds is different from 5. O The data suggest the population mean is not significantly different from 5 at a = 0.01, so there is sufficient evidence to conclude that the population mean number of cavities for twenty-year-olds is equal to 5. O The data suggest the populaton mean is significantly different from 5 at a = 0.01, so there is sufficient evidence to conclude that the population mean number of cavities for twenty- year-olds is different from 5.
