An insurance company determines that a linear relationship exists between the cost of fire damage in major residential fires and the distance from the house to the nearest fire station. A sample of 15 recent fires in a large suburb of a major city was selected. For each fire, the following variables were recorded: x= the distance between the fıre and the nearest fire station (in miles) y= cost of damage (in dollars) The distances between the fire and the nearest fire station ranged between 0.7 miles and 6.1 miles. The correlation between cost and distance is 0.961. Test if the correlation is significant at a=.10. O No, the correlation is not significant because 0.961 does not exceed the critical value. O Yes, the correlation is significant because 0.961 exceeds the critical value. O No, the correlation is not significant because 0.961 exceeds the critical value.

Please indicate which plot best summarizes the characeristic the characteristic (the name of the plot, not the function)i. Which plot best allows one to identify points that are outliers (i.e. far from the central location the data):A: Boxplot B: Histogramii. Which plot best allows one to assess the skew of the data: A: Boxplot B: Histogram

c. Identify the feature of the data that would be missed if part (b) was completed without constructing the scatterplot. Choose the correct answer below. O A. The scatterplot reveals a distinct pattern that is not a straight-line pattern. O B. The scatterplot reveals a distinct pattern that is a straight-line pattern with negative slope. O C. The scatterplot reveals a distinct pattern that is a straight-line pattern with positive slope. O D. The scatterplot does not reveal a distinct pattern. Using the linear correlation coefficient found in the previous step, determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables. Choose the correct answer below. O A. There is insufficient evidence to support the claim of a nonlinear correlation between the two variables O B. There is insufficient evidence to support the claim of a linear correlation between the two variables O C. There is sufficient evidence to support the claim of a…

how do I describe the "measures of center and variability" of a chart?

Which point would most likely be considered an outlier if it was added to the data in the table? (2,19),(5,11),(7,14) or (10,22)

The amount of time adults spend watching television is closely monitored by firms because this helps to determine advertising pricing for commercials. Complete parts (a) through (d). (a) Do you think the variable "weekly time spent watching television" would be normally distributed? If not, what shape would you expect the variable to have? A. The variable "weekly time spent watching television" is likely normally distributed. B. The variable "weekly time spent watching television" is likely skewed right, not normally distributed. C. The variable "weekly time spent watching television" is likely symmetric, but not normally distributed. D. The variable "weekly time spent watching television" is likely skewed left, not normally distributed. E. The variable "weekly time spent watching television" is likely uniform, not normally distributed. (b) According to a certain survey, adults spend 2.35 hours per day watching television on a weekday. Assume that the standard deviation for "time spent…

When creating the dot plot, how are multiple data points for a single score displayed? a. A larger size dot is used; the size of the dot is directly proportional to the number of data points. b. More than one dot is used; dots are placed side by side creating a wider interval. c. A dot plot is innappropriate when multiple data points exist for a single score. d. Multiple dots, representing each data point, are replaced on top of one another.

The value of a certain car when it was brand new with 0 mileage was $17,000 but the value dropped to $4,000 when the car acounulated 80,000 miles shown in the scatter plot below. Car's Mleage and Value S17.000 $2,000 Mileage Based on the data in the scatter plot, at what mileage was the car worth about $12,000? O 20,000 miles O 30,000 miles O 60,000 miles O 80,000 miles

A Cohort study was planned to identify the relationship between smoking and lung cancer. The number of people in smoker group was 500 people while the number of people in non- smokers group was 1000 people. The number of people with lung cancer was 250 people and 100 people in smokers group and non-smokers group respectively. Fill in the table below: Lung Cancer No disease diagnosed Smokers Non smokers Calculate the relative risk of lung cancer in smokers when compared with non- smokers.
