which of the following describes a study in which the researchers do not attempt to change the characteristics of those being studied?
A) Single-blind experiment
B) case-conteol study
C) Double-blind experiment
D) observational study

Solutions

Expert Solution

Correct option:

D) observational study

Explanation:

In Observational Study, the researcher simply measures the characteristics of the population by studying the individuals in the sample, but the researcher does not manipulate the variables of interest.

A paper describes a study in which researchers observed wait times in coffee shops in Boston. Both wait time and gender of the customer were observed. The mean wait time for a sample of 145 male customers was 85.6 seconds. The mean wait time for a sample of 141 female customers was 113.6 seconds. The sample standard deviations (estimated from graphs that appeared in the paper) were 50 seconds for the sample of males and 75 seconds for the sample...

One article describes a study of 81 randomly selected young adults with pierced tongues. The researchers found receding gums, which can lead to tooth loss, in 25 of the participants. (a) Construct a 95% confidence interval for the proportion of young adults with pierced tongues who have receding gums. (Don’t forget to check all conditions necessary to your construction!) (b) Write a sentence in which you correctly interpret the confidence interval you created. (c) Would the interval you found in...
