The following data were collected during the kind of sessions outlined in project 2 to be found at the end of Chapter 9 in the main text, when some students undertook various exercises such as jigsaw making, designing with shapes and so on. For each of the students, calculate:

(a) The learning rate using:

(i) the high-low method; and

(ii) the regression analysis method.

(b) The CAT and total times as if:
(i) 20 trials; and (ii) 30 trials had been completed.

(c) How many trials would need to be carried out for the total time to have been 700 seconds (keep your answer to two decimal places)?
