=+to a stress protocol and then removed and tested at various times after the protocol had been applied.

The accompanying data on x 5 time (min) and y 5 blood glucose level (mmol/L) was read from a plot:

x: 2 2 5 7 12 13 17 18 23 24 26 28 y: 4.0 3.6 3.7 4.0 3.8 4.0 5.1 3.9 4.4 4.3 4.3 4.4 x: 29 30 34 36 40 41 44 56 56 57 60 60 y: 5.8 4.3 5.5 5.6 5.1 5.7 6.1 5.1 5.9 6.8 4.9 5.7 Use the methods developed in this chapter to analyze the data, and write a brief report summarizing your conclusions (assume that the investigators are particularly interested in glucose level 30 min after stress).
