In an article regarding children who were raised by their grandparents, a researcher considered the rates of children (under 18 years of age) living in California with grandparents as their primary caretakers. The data set below includes a simple random sample of 12 percentages (rounded to the nearest tenth) from California counties of children under 18 living with grandparents. Identify the potential outlier(s), if any. 5.8,4.3,4.0,5.7,5.6,5.1,6.1,4.1,4.5,4.4,6.4,4.9

14. The following are examples of DNA repair mechanisms in eukaryotic and/or prokaryotic cells: Base excision repair, Nucleotide excision repair, Nonhomologous end joining, Homologous recombination, SOS repair, and Microhomology mediated end joining. For each of the following examples, state which repair mechanism was most likely involved. If more than one is possible, choose only one. A. Bacteria cells exposed to a mutagenic chemical show small regions with many substitution mutations: SOS repair B. A 5kb inversion in a chromosome that contains no other mutations: Homologous recombination C. A mutagen results in the changing of a DNA base to uracil in a way that does not distort the double helix: Base excision repair D. Mitotically dividing cells exposed to X rays show crossovers: Homologous recombination E. Treatment with UV radiation results in thy nine dimers: Nucleotide excision repair

A 2018 poll of 3608 randomly selected users of a social media site found that 1841 get most of their news about world events on the site. Research done in 2013 found that only 49% of all the site users reported getting their news about world events on this site. a. Does this sample give evidence that the proportion of site users who get their world news on this site has changed since 2013? Carry out a hypothesis test and use a 0.05 significance level. a. State the null and alternative hypotheses. Let $p$ be the proportion of site users who get their world news on the site. $H_0: p = 0.49$ $H_1: p \neq 0.49$ (Type integers or decimals. Do not round.) Compute the z-test statistic. z = (Round to two decimal places as needed.) Compute the $p$-value p-value = (Round to three decimal places as needed.) Reject $H_0$ or do not reject $H_0$ and interpret the conclusion. Choose the correct answer below. $\bigcirc$ A. Do not reject $H_0$. The percentage is significantly different from 49%. $\bigcirc$ B. Reject $H_0$. The percentage is significantly different from 49%. $\bigcirc$ C. Do not reject $H_0$. The percentage is not significantly different from 49%. $\bigcirc$ D. Reject $H_0$. The percentage is not significantly different from 49%. b. The 95% confidence interval for the population proportion is ( (Round to four decimal places as needed.) The result of the 95% confidence interval with the result of the hypothesis test performed in part (a) because the value of $p_0$ is the 95% confidence interval
