We are interested in studying cigarette demand by young adults. Lets consider thefollowing model:ncaj = β0 + β1price + β2age + β3income + uwhere ncaj is monthly cigarette consumption in packs, price is the price of a pack ofcigarettes in dollars, age is age in years, and income is annual income in thousandsof dollars.
Consider now an extension of the model that allow the effect of theprice to differ by age. Holding all other factors fixed, is the effect of price onncaj constant? (This part is theoretical and you do not have to estimate themodel.)
Consider a model with an interaction term between being female and being married. The dependent variable is the log of the
hourly wage:
log(wage) = 0.151 - 0.038 female + 0.1 married - 0.301 female* married + 0.079 educ + 0.027 exper+0.029 tenure

The Different Effects of Excitation and Inhibition in Neural Circuit (series #1)|
Neural circuit consists of polysynaptic neural network, combination of excitatory and inhibitory
neurons. This exercise helps to understand the effects of excitation and inhibition in the nervous
system.
Our body is dynamically active under physiology condition. As a result, there are basal levels of
activity such as 70 beats/min of heart rate at resting condition. Either increased or decreased
activities are relative to the baseline.
The effects of excitation are easily understood---one neuron activates another neuron. However,
when inhibition is introduced into circuits, analysis become more complicated. In fact, the
numbers of inhibitory neurons in the circuit determine the final effect of the circuit, which can be
excitation or inhibition, on the target organ or area.
We assume all excitatory and inhibitory neurons are glutamate and GABA neurons, respectively,
in this practice sheet. The glutamate and…

- Environmental conditions can affect the growth of coral. To study this, a researcher examined a species of coral that is found in the Caribbean Sea and the Gulf of Mexico. At 12 localities, he determined the average annual calcification rate of coral over a period of several years and the average annual maximum sea surface temperature during the same period. Calcification rate affects the growth of coral, with higher rates corresponding to greater growth. The table contains data for these 12 localities.

- Ramp metering is a traffic engineering idea that requires cars entering a freeway to stop for a certain period of time before joining the traffic flow. The theory is that ramp metering controls the number of cars on the freeway and the number of cars accessing the freeway, resulting in a freer flow of cars, which ultimately results in faster travel times. To test whether ramp metering is effective in reducing travel times, engineers conducted an experiment in which a section of freeway had ramp meters installed on the on-ramps. The response variable for the study was speed of the vehicles. A random sample of 15 cars on the highway for a Monday at 6 p.m. with the ramp meters on and a second random sample of 15 cars on a different Monday at 6 pm with the meters off resulted in the following speeds (in miles per hour).

The method was developed in the late 1940s at the University of Chicago by Willard Libby, who received the Nobel Prize in Chemistry for his work in 1960. It is based on the fact that carbon- 14 is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting carbon-14 combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire carbon-14 by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of carbon-14 it contains begins to decrease as the carbon-14 undergoes radioactive decay. Measuring the amount of carbon-14 in a sample from a…arrow_forward

They obtained the data in the screenshot, which contains three variables: FTF – the percentage of fast twitch fibres in the muscle. T1 – the T1 relaxation time measured in ms. T2 – the T2 relaxation time measured in ms. Perform a multiple linear regression using the model FTF = b0 + b1T1 + b2T2. i) What are the values of the three coefficients in the equation? ii) What is the F statistic and P value for the regression? Do these indicate that the regression is significant? iii) Does adding the other NMR relaxation time, T2, to the predictive equation significantly improve the ability of NMR spectroscopy to predict muscle fibre type?
