A few of fellow classmates in lab made similar observations as you. They made wet mounts of Blepharisma and measured their diameters at the beginning of lab and at the end. Knowing that the water would evaporate over time, thev wanted to see if the diameters of the Blepharisma would significantly increase over time. Their collected data can be seen below: Area to the right (a) 0.05 0.10 0.025 0.01 0.005 0.001 0.0005 df 0.20 1 1.376 1.963 3.078 6.314 12.71 31.82 63.66 318.3 2 1.061 1.386 1.886 2.920 4.303 6.965 9.925 22.33 31.60 3 0.978 1.250 1.638 2.353 3.182 4.541 5.841 10.21 40.941 1.190 1.533 2.132 2.776 3.747 4.604 7.173 8.610 5 0.920 1.156 1.476 2.015 2.571 3.365 4.032 5.893 6.869 6 0.906 1.134 1.440 1.943 2.447 3.143 3.707 5.208 5.959 70.896 1.119 1.415 1.895 2.365 2.998 3.499 4.785 5.408 8 0.889 1.108 1.397 1.860 2.306 2.896 3.355 4.501 9 0.883 1.100 1.383 1.833 2.262 2.821 3.250 4.297 Time 1 Width Time 2 Width 0.15 636.6 (um) (um) 12.92 50 25 30 20 40 30 5.041 4.781 1. 69m s) Based on the group's research interests, what would be an appropriate a.eernative hypothesis?
