- Why is it a critical and challenging part of the model-building process to determine the appropriate values?arrow_forwardQuestion 1 part B. Thanksarrow_forwardYou may need to use the appropriate technology to answer this question. An automobile dealer conducted a test to determine if the time in minutes needed to complete a minor engine tune-up depends on whether a computerized engine analyzer or an electronic analyzer is used. Because tune-up time varies among compact, intermediate, and full-sized cars, the three types of cars were used as blocks in the experiment. The data obtained follow.

- PLEASE DON'T UPLOAD A PICTURE OF THE ANSWER. PLEASE TYPE IT SO I CAN COPY AND PASTE IT INTO MY NOTES. THANK YOU!! Chi-Square Good of Fit Problem: Automobile insurance is much more expensive for teenage drivers than for older drivers. To justify this cost difference, insurance companies claim that the younger drivers are much more likely to be involved in costly accidents. To test this claim, a researcher obtained information about registered drivers from the Department of Motor Vehicles (DMV) and selected a sample of n = 300 accidents reports from the police department. The DMV reports the percentage of registered drivers in each age category as follows: 16% are younger than age 20,; 28%are 20 to 29 years old;and 56% are age 30 and older. The number of accidents reports for each age group is as follows: Under age 20 Age 20-29 Age 30 and older 68 92 140 Is…arrow_forwardSuppose a researcher wants to see if the proportion of college educated adults is higher in New York compared to Florida.

- In designing a model, there can be a trade‐off between missing out on an important independent variable and including an extra unnecessary one. Discuss this trade‐off in terms of: a) Degrees of freedom and Unbiased or bias of slope estimatesarrow_forwardDistinguish between Research methods and Research methodology.arrow_forward2. Two different statistics. Statistic A and Statistic B. are used to estimate the same population parameter. Statistic A has less variability than Statistic B and Statistic A has less bias than Statistic B. Using the axes below, draw parallel dotplots showing 10 values of each statistic that are consistent with these characteristics. Assume that the parameter value is at the arrow on the axes.

- Define Path Analysis?arrow_forwardThe Minister of National Security in Trinidad and Tobago is interested in determining the factors that influence the number of crimes that are reported. You are tasked to develop a model using the appropriate variables. The following variables are utilized: X1 = total overall reported crime rate per 100,000 residents X2 = reported violent crime rate per 100,000 residents X3 = % of people 25 years+ with 4 yrs. of high school X4 = % of 16 to 19-year-olds not in high school and not high school graduates.
