Answer:A) Age × Sex Interaction:
In this context, an Age × Sex interaction would mean that the relationship between age (in years) and FEV (forced expiratory volume) is different for males and females. In other words, the effect of age on FEV is not the same for both sexes.
B) Visualization:
To visualize the relationship among FEV, Age, and Sex, you can create scatterplots or box plots. You might want to create separate plots for males and females, plotting FEV against Age. This will help you see if there are any notable patterns or differences between the sexes.
C) Age × Sex Interaction Assessment:
Based on the plot, you can assess whether there appears to be an Age × Sex interaction. Look for patterns where the relationship between Age and FEV differs between males and females. If the lines or patterns on the plots for males and females diverge or cross, this suggests an interaction.
D) Linear Regression Model:
You can use linear regression to relate FEV to Age and Height. The regression equation might look like:
FEV = β0 + β1 * Age + β2 * Height + ε
E) Mean FEV Estimation:
To estimate the mean FEV for 14-year-old children who are 66 inches tall, you would substitute the values into the regression equation obtained in part D and calculate the predicted FEV. The interval can be constructed based on the standard error of the prediction.
F) Hypothesis Testing:
For testing H0: βAge = βHeight = 0, you can perform an F-test or assess the significance of each coefficient in the regression model. The statistic, P-value, and conclusion can be derived from the regression output.
G) Confounding Assessment:
Calculate Pearson correlations between FEV and Height and FEV and Age. Then calculate partial correlations controlling for the other predictor. Assess if controlling for one predictor changes the relationship between FEV and the other predictor.
H) Variance Inflation Factors (VIFs):
Compute VIFs for the model with all three predictors (Age, Height, Sex). VIFs help identify multicollinearity. Interpret VIF values to assess whether multicollinearity is a concern.
I) Model Selection:
Starting with a full model, gradually remove interactions and terms that do not contribute significantly to the model's explanatory power. Consider the AIC or BIC to guide model selection. Justify your choice of the final model based on statistical significance and interpretability.
J) Regression Assumptions:
Address regression assumptions such as linearity, independence of errors, homoscedasticity, and normality of residuals. Use diagnostic plots and statistical tests to assess these assumptions and make corrections if necessary.
Please note that this is a complex statistical analysis project that involves data manipulation, visualization, and modeling. You may need to use statistical software like R, Python, or specialized statistical packages to perform these tasks and draw meaningful conclusions from your data.

B: Cranial nerves
C: Autonomic nereves
Afferent nerves send information from the body sensors to the Central Nervous System.Thus, option A is correct.
Afferent nerves are sensory nerves that carry information from the body's sensory receptors to the central nervous system (CNS). This information can be about the environment, such as touch, pain, temperature, and vision, or it can be about the body's internal state, such as blood pressure, heart rate, and blood sugar levels.
Cranial nerves are a special type of afferent nerve that originates in the brain. They are responsible for a variety of functions, including vision, hearing, smell, taste, and facial expression.
Autonomic nerves are a type of efferent nerve that controls involuntary functions of the body, such as heart rate, blood pressure, and digestion. They do not carry information from the body to the CNS.
So the correct answer is A: Afferent nerves.
