The average number of cavities that thirty-year-old Americans have had in their lifetimes is 6. Do twenty-year-olds have a different number of cavities? The data show the results of a survey of 13 twenty-year-oldswho were asked how many cavities they have had.

Based on this, we should Select an answerv the null hypothesis.g. Thus, the final conclusion is that ...O The data suggest the populaton mean is significantly different from 6 at a = 0.01, so there issufficient evidence to conclude that the population mean number of cavities for twenty-year-olds is different from 6.O The data suggest that the population mean number of cavities for twenty-year-olds is notsignificantly different from 6 at a = 0.01, so there is insufficient evidence to conclude that thepopulation mean number of cavities for twenty-year-olds is different from 6.O The data suggest the population mean is not significantly different from 6 at a = 0.01, sothere is sufficient evidence to conclude that the population mean number of cavities fortwenty-year-olds is equal to 6.h. Interpret the p-value in the context of the study.O There is a 0.36950232% chance of a Type I error.O If the population mean number of cavities for twenty-year-oids is 6 and if you survey another13 twenty-year-olds, then there would be a 0.36950232% chance that the sample mean forthese 13 twenty-year-olds would either be less than 4.77 or greater than 7.23.

This histogram shows the heights of 20 students in a statistics class. Explain why it is not appropriate to find summary statistics for this distribution. Frequency 4- 3- 2- 1- T 0+ 60 65 70 75 Height (Inches) Choose the correct answer below. OA. Since there appear to be two modes, this data probably represents men and women and should be split into those two groups before finding any summary statistics. OB. The number of data values is too small for summary statistics to be meaningful. OC. Since the data appear to be bimodal, no other measures of center or spread can be calculated. OD. Since the distribution is not symmetric, summary statistics would be meaningless.

Nicole has a popular blog about cooking and nutrition and regularly posts articles and videos. She has collected data about the length of time that viewers spent watching two of her recent videos. For each video, she recorded the amount of time (in minutes) that each of 102 viewers spent watching it. The histograms below show the distributions of the two data sets. Each histogram shows time (in minutes) on the horizontal axis and the number of viewers on the vertical axis. The means and standard deviations for the data sets are also given.
