# Which distribution (standard normal or Student's t) did you use? Why? Do you need information about the soil water content distributions?

The following data represent soil water content for independent random samples of soil taken from two experimental fields growing bell peppers Soil water content from field I: x1.n1=72 15.111.210.310.816.68.39.112.39.114.3 10.716.110.215.28.99.59.611.31411.3 15.611.213.89.08.48.21213.911.616 9.611.48.48.014.110.913.213.814.610.2 11.513.114.712.510.211.811.012.710.310.8 11.012.610.89.611.510.611.710.19.79.7 11.29.810.311.99.711.310.4121110.7 8.811.1 Soil water content from field II: x2.n2=80 12.110.213.68.113.57.811.87.78.19.2 14.18.913.97.512.67.314.912.27.68.9 13.98.413.47.112.47.69.9267.37.4 14.38.413.27.311.37.59.712.36.97.6 13.87.513.38.011.36.87.411.711.87.7 12.67.713.213.910.412.87.610.710.710.9 12.511.310.713.28.912.97.79.79.711.4 11.913.49.213.48.811.97.18.51414.2

Student's t distribution, because the population standard deviations 0, and 72 are unknown and we which to estimate the difference between means.
Note: if the population standard deviations o1 and oz, then we use the standard normal distribution.
