Are these two variables dependent at the population level?

An educator wants to determine whether a new curriculum significantly improves standardized test scores for third grade students. She randomly divides 90 third-graders into two groups. Group 1 is taught using the traditional curriculum, while group 2 is taught using the new curriculum. At the end of the school year, both groups are given the standardized test and the mean scores are compared. Determine whether the sampling is dependent or independent. Indicate whether the response variable is qualitative or quantitative. Determine whether the sampling is dependent or independent. A. This sampling is independent because the individuals selected for one sample do not dictate which individuals are to be in a second sample. B. The sampling is independent because the individuals selected to be in one sample are used to determine the individuals to be in the second sample. C. The sampling is dependent because the individuals selected to be in one sample are used to determine the individuals to be in the second sample. D. The sampling is dependent because the individuals selected for one sample do not dictate which individuals are to be in a second sample. Indicate whether the response variable is qualitative or quantitative. A. The variable is quantitative because it is a numerical measure. B. The variable is qualitative because it classifies the individual. C. The variable is quantitative because it classifies the individual. D.

Suppose you took a survey designed to assess criminal justice students' attitudes towards ending cash bail in California. You asked 100 students (randomly sampled) how much they'd be willing to pay to fund community supervision programs over the current cash bail system. There is another question that asks students if they believe reforming cash bail is a serious issue. Select all correct answers. {} Students answer yes or no to the question of whether they believe cash bail reform should occur. This means the samples are independent. {} Students answer yes or no to the question of whether they believe cash bail reform should occur. This means the samples are dependent. {} The response variable is the amount of tax a student is willing to pay to cover community supervision costs. {} The response variable is a student's belief that cash bail needs to be reformed.
