- 20) A study in the Los Angeles Times reported that the number of liquor stores in a neighborhood has a strong positive linear association with the amount of crime in that neighborhood. What can you determine about the relationship between the number of liquor stores and the amount of crime? Neighborhoods with a higher number of liquor stores tend to have a higher amount of crimes. People who live in neighborhoods with more liquor stores commit more crimes. If we decrease the number of liquor stores in a neighborhood, the amount of crimes will decrease. No conclusions can be drawn without seeing a scatterplot of the data.5). What does having a linear relation in a scatterplot mean? 6). Which type of graph would be most appropriate for predicting one variable based on another variable? For example, predicting graduation rates based on SAT scores.A car dealer randomly selects 24 automatic cars and 21 manual cars to compare the fuel efficiency of the engines. A dotplot of the data is shown below, where each dot represents the fuel efficiency of one car (km/l) in the sample (greater fuel efficiency is indicated by larger numbers). Choose TWO options that best describes what the graph tell you about the fuel efficiency of the cars in the sample: a) fuel efficiency for manual cars is positively skewed. b) manual cars have the higher median fuel efficiency. c) the least fuel efficient car in the sample is manual. d) the most fuel efficient car in the sample is automatic. e) automatic have the larger range. d) fuel efficiency for manual cars is negatively skewed.
- When wildebeest are more abundant, they graze the grass more heavily, so there are fewer fires and moretrees grow. Lions feed more successfully when there are more trees, so the lion population increases. Thedata on one part of this cycle, wildebeest abundance (in thousands of animals) and the percent of the grassarea that burned in the same year are on the spreadsheet. To what extent do these data support the claim that more wildebeest reduce the percent of grasslands that burn? How rapidly does burned area decrease as the number of wildebeest increases? To answer these questions, create a scatterplot and add the regression line. Describe the scatterplot. Interpret the slope and intercept in context of the problem. Does the intercept explanation make sense in the real world? Find the correlation coefficient and coefficient of determination. What do they tell us about the relationship between number of wildebeest and percent of grassland burned? Beest (in 1000s) Percent Burned…A standard test of emotional intelligence results in a set of seven sub-test scores, but not a total score. What can we assume about the factor analysis of scores from this test? Oa. The test is mukidimensional and the dimensions are correlated. Ob. The test is multidimensional but the dimensions are not correlated. OC. The test is unidimensional. O d. The test is multidimensional and the dimensions are hierarchically organized. zmeroncereneroncra arromlichnmerccenrara ace To accomelish thisSahar Rasoul-Math 7 End of Yea X Gspy ninjas book-Google docs.google.com/spreadsheets/d/1j5MotWzsc0V1V3Qyl4rbP_OFOUotaNXCIIFax> Copy of Copy of Col... 8.8 Sahar Rasoul - Math 7 End of Year Digital Task Cards Student Version ☆ File Edit View Insert Format Data Tools Extensions Help Last edit was 5 minu $ % .0 .00 123 Century Go... ▼ 18 Y BIS fx| =IF(B4="Question 1", Sheet2!

- Please answer the question. Asap. Thank you.A sports psychologist studied the effect of a motivational program on number of injuries in one year among players of three different sports (baseball, football, and basketball). Players were randomly assigned to one of two conditions: either participate in a motivational program or none (control). Data was collected on the number of injuries sustained by each athlete that season. Question: As taught in 510/515, what is the most appropriate graph if all main effects and interactions in this scenario were significant?in what year was NHS PPP seen to be most effective same for sugar tax and phsycial and healthy eating campains. on type 2 diabetes , provide a stastical graph along side raw data for each
- 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.)Why won't the whiteboard image show up?A city planner wants to work with community leaders to develop a system of walker-friendly paths between the city's five parks. Since cost is an issue, the planner collects data on the cost of each park-to-park route. The planner uses the Nearest Neighbor method to determine an estimate of a least cost system of sidewalks that would allow a walker to visit each park once and return to the park where the walker has parked his/her car. The weighted graph below shows the cost of each possible path in thousands of dollars. .236' 239 124. 225 131 163 A 168 109 120 11 E Starting and ending at vertex A, what is the minimum cost to construct paths as estimated by the Nearest-Neighbor method? (note: The values on the graph are thousands of dollars, so you will need to append three zeros to your response. For example, if you get a minimum cost of 123, you would enter 123000.)
