- 2 Many students over the last couple of years have been earning money as social networking service influencers. The amount of influencers and their popularity has been growing steadily. The top 50 social networking service influencers have over 3 billion followers together. Unfortunately, this development has a downside for dogs. According to a recent newspaper article, dogs deemed less playful for video sharing social networking services are being dumped at shelters. The general perception of playfulness disproportionately affects older dogs. The accompanying table gives the data for a random selection of dogs from a local shelter for a correlation of age and days. Construct a 90% confidence interval to estimate the average number of days a dog that is 4 years old will stay at the shelter. Click the icon to view the data table. (CCECOP) Determine the upper and lower limits of the 90% confidence interval. UCL= days LCL = days (Round to two decimal places as needed.)Data from the Bureau of Labor Statistics indicates that in a certain month, 36.8% of the labor force had a high school diploma or fewer years of education, 29.9% had some college or an associate's degree, and 33.3% had a bachelor's degree or more education. Of those with a high school diploma or fewer years of education, 6.8%were unemployed. Of those with some college or an associate's degree, 4.7% were unemployed, and of those with a bachelor's degree or more education, 2.9%were unemployed. Find the probability that a randomly chosen labor force participant has some college or an associate's degree given that he or she is unemployed.The National Safety Board wants to determine the effect of seat belt use on saving lives.

- The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 9.7% of his customers buy a magazine and he thinks that he might be able to use the display space to sell something more profitable. Before making a final decision, he decides that for one day he will keep track of the number of customers that buy a magazine. Assuming his suspicion that 9.7% of his customers buy a magazine is correct, what is the probability that exactly 6 out of the first 13 customers buy a magazine? 0.000305894 0.00100664 0.000699781 0.000778757 0.000204114 0.000326183In a survey, it was found that 72%of the population of a certain urban area lived in single-family dwellings and 28% in multiple housing. One year later, of those who had been living in single-family dwellings, 89%still did so, but 11% had moved to multiple-family dwellings. Of those in multiple housing, 94%were still living in that type of housing, while 6%had moved to single-family housing. Assume that these trends continue. (a) Write a transition matrix using this information. Set it up so that the first row and first column represent single-family dwellings and the second row and second column represent multiple housing.Data from the Bureau of Labor Statistics indicates that in a certain month, 35.7% of the labor force had a high school diploma or fewer years of education, 29.4% had some college or an associate's degree, and 34.9% had a bachelor's degree or more education. Of those with a high school diploma or fewer years of education, 5.5% were unemployed. Of those with some college or an associate's degree, 4.4% were unemployed, and of those with a bachelor's degree or more education, 2.4% were unemployed. Find the probability that a randomly chosen labor force participant has some college or an associate's degree given that he or she is unemployed. 12 The probability is 0 (Type an integer or decimal rounded to three decimal places as needed.)

A psychologist at a private psychiatric hospital was asked to determine whether there was any clear difference in the length of stay of patients with different categories of diagnosis. Looking at the last four patients in each of the three major categories, the results (in terms of weeks of stay) were as follows: Diagnosis Category Cognitive Disorders 12, Affective Disorders Drug-Related Conditions 7. 8. 6. 8. 10 5. 6. 12 11 10 Mı=6 M2 = 10 M3 = 10 %3D %3D SS, = 2 SS2 = 10 SS2 = 8 SSBetween= 42.67 a.

The National Institutes of Health (NIH) have partnered with the Healthcare Cost and Utilization Project (HCUP) to gather data on opioid-related deaths and hospitalizations. These data include information about inpatient stays, emergency department visits, age, sex, income, and opiod-related use. For a given patient admitted to a hopsital for an opioid-related event, identify which of these events are disjoint.
