This exercise requires the use of a computer and software. Some of the answers may be calculated manually. Use a 5% significance level. To measure the extent of cigarette smoking around the world, random samples of adults in Denmark, Finland, Norway, and Sweden were drawn. Respondents were asked whether they smoke (2 = Yes, 1 = No). Country Smoker? Denmark Finland Norway Sweden 1 423 395 394 433 2 77 105 106 67 Can we conclude that there are differences in smoking between the four Scandinavian countries? State the hypotheses. 1. $H_0$: The two variables, smoking status and Scandinavian country, are not mutually exclusive. $H_1$: The two variables, smoking status and Scandinavian country, are mutually exclusive. 2. $H_0$: The two variables, smoking status and Scandinavian country, are mutually exclusive. $H_1$: The two variables, smoking status and Scandinavian country, are not mutually exclusive. 3. $H_0$: The two variables, smoking status and Scandinavian country, are independent. $H_1$: The two variables, smoking status and Scandinavian country, are dependent. 4. $H_0$: The two variables, smoking status and Scandinavian country, are dependent. $H_1$: The two variables, smoking status and Scandinavian country, are independent. Calculate the value of the test statistic. (Round your answer to two decimal places.) Use technology to find the p-value. (Round your answer to four decimal places.) $p-value = $

To determine the proportion of treasure chests that contain legendary items, a group of adventurers recorded the number of legendary items found in 54 treasure chests. The 95% confidence interval (-0.0265, 0.1935) was constructed based on their findings. Answer the following: a.) Which of the following is the correct interpretation of the confidence interval? We are 95% confident that the sample proportion of treasure chests that contain legendary items is between -0.0265 and 0.1935. 95% of all treasure chests will contain between -0.0265 and 0.1935 legendary items. There is a 95% chance that a treasure chest will contain between -0.0265 and 0.1935 legendary items. We are 95% confident that the population proportion of treasure chests that contain legendary items is between -0.0265 and 0.1935. b.) Compute the best point estimate and margin of error from the confidence interval. The best point estimate is The margin of error is c.) Which of the following claims can be made about the proportion of treasure chests that contain legendary items from the given confidence interval? More than 15% of treasure chests will contain a legendary item. Less than 15% of treasure chests will contain a legendary item. Less than 24% of treasure chests will contain a legendary item. More than 24% of treasure chests will contain a legendary item.

How does the CRISPR/Cas9 system generate small indels associated with the DNA target sequence? Question 9 options: Cas9 nuclease activities generate a blunt double-stranded DNA break just upstream of the 20 nucleotides targeted by the sgRNA; in the absence of a donor DNA, this blunt-end DNA break will be repaired by homology directed repair (HDR). Cas9 nuclease activities generate a blunt double-stranded DNA break just upstream of the 20 nucleotides targeted by the sgRNA; in the absence of a donor DNA, this blunt-end DNA break will be repaired by nonhomologous end joining (NHEJ). Cas9 nuclease activities generate a blunt double-stranded DNA break 3 nucleotides upstream of a PAM site, which is immediately downstream of the target sequence defined by the guide of the sgRNA; in the absence of a donor DNA, this blunt-end break will be repaired by nonhomologous end joining NHEJ.
