Below are a set of heights (in inches) and GPA scores for a sample of 6 students Height GPA 60 55 3.2 62 58 49 61 4.0 3.7 3.9 2.4 2.8 a. Find the correlation coefficient (r) for these two variables by hand: Find the mean and standard deviation for each variable Find the equation of the regression line to predict GPA from height by hand: Find the equation of the regression line to predict height from GPA by hand b. c. d. and e. Based on this data, what is the GPA prediction for a student who is 56 inches tall? f How good is this prediction?

It appears that people who are mildly obese are less active than leaner people. one study looked at the average number of minutes per day that people spend standing or walking. among mildly obese people, the mean number of minutes of daily activity (standing or walking) is approximately normally distributed with mean 376 minutes and standard deviation 64 minutes. the mean number of minutes of daily activity for lean people is approximately normally distributed with mean 528 minutes and standard deviation 107 minutes. a researcher records the minutes of activity for an srs of 7 mildly obese people and an srs of 7 lean people. use z-scores rounded to two decimal places to answer the following: what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 mildly obese people exceeds 420 minutes? what is the probability (image for it appears that people who are mildly obese are less active than leaner people. one study looked at the averag0.0001) that the mean number of minutes of daily activity of the 6 lean people exceeds 420 minutes?
