The data below are the weights (in lbs) and heights (in inches) of some members of FSUâs Dept of Statistics. We would like to come up with a linear model to predict weight from height. Weights (lbs) 157 158 175 210 194 160
Heights (in.) 64 70 71 68 70 66

Required:
a. Use the data and your calculator to find the slope of the linear model.
b. Use the data and your calculator to find the y-intercept of the linear model.

The probability that a u. s. resident has traveled to canada is 0.18 and to mexico is 0.09. a. if traveling to canada and traveling to mexico are independent events, what is the probability that a randomly-selected person has traveled to both? (page 109 in the book may ) b. it turns out that only 4% of u. s. residents have traveled to both countries. comparing this with your answer to part a, are the events independent? explain why or why not. (page 119 may ) c. using the %’s given, make a venn diagram to display this information. (don’t use your answer to part a.) d. using the conditional probability formula (page 114 in the book) and the %’s given, find the probability that a randomly-selected person has traveled to canada, if we know they have traveled to mexico.
