What is the equation of the best model? Select the correct choice below and fill in the answer boxes to complete your choice. Enter only nonzero values. (Type integers or decimals rounded to three decimal places as needed.) O A. y= + In x O B. y= + X O C. y= O D. yE X 2 O E. y= X + ) x+Fm experiment involves dropping a loall and recording the distance it falls {y} for different times [3:] after it was released. Construct a scatterolot and identify the mathematical model that best ts the given data. Assume that the model is to be used only.r for the scope of the given data, and consider only linear. quadratic. logarithmic. exponential. and power models.

Since the correlation coefficient r is there sufficient evidence to support the claim of a linear correlation.For a data set of brain volumes (cm ) and IQ scores of eleven males, the linear correlation coefficient is r = 0.401. Use the table available below to find the critical values of r. Based on a comparison of the linear correlation coefficient r and the critical values, what do you conclude about a linear correlation?

Write a statement that interprets the P-value and includes a conclusion about linear correlation. The P-value indicates that the probability of a linear correlation coefficient that is at least as extreme is %, which is so there sufficient evidence to conclude that there is a linear correlation between brain volume and IQ score in males.

The 20 pairs of measurements yield x = 103.81, y = 100.95, r= 0.949, P-value = 0.000, and y = 2.98 + 0.94x, where x represents the IQ score of the younger child. Find the best predicted value of y given that the younger child has an IQ of 110? Use a significance level of 0.05.
