An educator wants to determine whether a new curriculum significantly improves standardized test scores for third grade students. She randomly divides 80 third dash 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. 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. B. The sampling is dependent because the individuals selected for one sample do not dictate which individuals are to be in a second sample. C. This sampling is independent because the individuals selected for one sample do not dictate which individuals are to be in a second sample. D. 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. Indicate whether the response variable is qualitative or quantitative. A. The variable is quantitative because it is a numerical measure. B. The variable is quantitative because it classifies the individual. C. The variable is qualitative because it classifies the individual. D. The variable is qualitative because it is a numerical measure.

Answer #1

This is an interesting question! Please find the solution below:

1. Determine whether the sampling is dependent or independent.

C. This sampling is independent because the individuals selected for one sample do not dictate which individuals are to be in a second sample.

The two samples are independent of each other. The individuals selected in the first sample have no relations with the individuals selected in the second sample.

2. Indicate whether the response variable is qualitative or quantitative.

A. The variable is quantitative because it is a numerical measure.

The response variable is the mean scores which are numerical quantities.

A researcher wishes to examine whether time of day (morning versus afternoon) affects the memory of older and younger participants. He obtains a sample of 40 older individuals and 40 younger individuals and gives them a passage to read. They are later given a test over the passage (scores on the test could range from 0 to 30). Half of the individuals are randomly assigned to read the passage and take the test in the morning, and the other half...

To determine whether training in a series of workshops on creative thinking increases IQ scores, a total of 70 students are randomly divided into treatment and control groups of 35 each. After two months of training, the sample mean IQ (–X1) for the treatment group equals 110, and the sample mean IQ (–X2) for the control group equals 108. The estimated standard error equals 1.80.

A medical researcher wants to determine whether a drug changes the body’s temperature. Seven test subjects are randomly selected, and the body temperature (in degrees Fahrenheit) of each is measured. The subjects are then given the drug and after 20 minutes, the body temperature of each is measured again. The results are listed below. Use significance level α = 0.05, and we assume that the body temperatures are normally distributed.pleae show work t-Test: Paired Two Sample for Means Initial Temperature...

Dr. Calvin Broadus wants to determine whether marijuana influences anxiety. He draws a sample of n = 16 individuals. The population from which they were selected exhibit a score of µ = 30 on an anxiety measure. After “treatment” is administered to the individuals, the sample mean is found to be M = 33 and the sample variance is s2 = 64. Is this a one-tailed or two-tailed test? One-tailed Two-tailed If the researcher decides to test at the α...

1. Marcus wants to determine how age and weight are related to exercise preference in his town. He selects a simple random sample of 75 overweight individuals from the 25- to 35-year age group and records their age, weight, and exercise preference (sports, Pilates/yoga, dancing, none). He also selects an independent simple random sample of 50 normal-weight individuals from the 40- to 50-year age group and records the same information. Which is the most important observation about Marcus's plan? a....
