A researcher wants to describe how fine motor skills change as a group of infants age from 18 to 24 months. Describe how this study could be done as a cross-sectional design. Next, describe how this study could be done as a longitudinal study. Although the cohort effect can be a serious problem for cross-sectional research, it is not a problem for longitudinal designs. Explain why not.

Part of why cocaine is so dangerous is that it blocks dopamine receptors. Researchers conducted an experiment to test whether a person’s perception of the quality of the high achieved from taking cocaine (the response) can be predicted based on the percent of dopamine receptors that were blocked by the cocaine (the predictor). For the following data (here: https://github.com/lisamanne/biostats_data/raw/main/cocaine_high_dopamine_receptors.csv) , conduct a hypothesis test of whether such a predictive relationship exists. List: your null hypothesis, the p-value you find, your conclusion, the equation of the predictive relationship, and a plot of the data, with the line overlaid.
