You are radioactive. Your friend holds a Geiger counter up to you each day for a month and measures the amount of radiation you emit (units: log-rads):

day (x-axis):
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 , 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30

emission rate (y-axis):
4.992978, 4.649644, 4.207954, 4.272358, 3.754023, 4.620570, 4.413982, 3.962083, 3.261861, 3.174920, 3.787362, 4.231206, 3.649822, 3.589744, 4.488566, 3.501440, 3.216620, 3.138885, 3.151528, 3.138287, 3.151362, 3.027574, 2.938005, 2.550175, 3.146502, 2.927469, 2.950873, 3.026285, 2.095725, 1.933463, 2.938397

Compute the best fit line to the data. Report:
(a) The slope coefficient, β1.
(b) The intercept coefficient, βo.
(c) The standard error of the residuals.
(d) The Adjusted R-squared correlation coefficient Adjusted R².
(e) Is the slope coefficient significant at, at least the 95% level of confidence?
(f) Is the intercept coefficient significant at, at least the 95% level of confidence?
(g) Given this data and the fit results, what is an equally valid relation between the explanatory and response variables? (Note m≠0 and b≠0)

a) y = mx + 0
b) y = x
c) y = mx + b
d) y = 0x + 0

Each of the following data sets has a mean of x = 10. (i) 8 9 10 11 12 (ii) 7 9 10 11 13 (iii) 7 8 10 12 13 (a) without doing any computations, order the data sets according to increasing value of standard deviations. (i), (iii), (ii) (ii), (i), (iii) (iii), (i), (ii) (iii), (ii), (i) (i), (ii), (iii) (ii), (iii), (i) (b) why do you expect the difference in standard deviations between data sets (i) and (ii) to be greater than the difference in standard deviations between data sets (ii) and (iii)? hint: consider how much the data in the respective sets differ from the mean. the data change between data sets (i) and (ii) increased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). the data change between data sets (ii) and (iii) increased the squared difference îł(x - x)2 by more than data sets (i) and (ii). the data change between data sets (i) and (ii) decreased the squared difference îł(x - x)2 by more than data sets (ii) and (iii). none of the above
