13. A pharmaceutical company has developed a new drug for
depression. There is a concern, however, that the drug also
raises the blood pressure of its users. A researcher wants to
conduct a test to validate this claim. Would the manager of the
pharmaceutical company be more concerned about a Type I
error or a Type II error? Explain.

Recent research has questioned its effectiveness [“Reassessment of Rain Enhancement Experiments and Operations in Israel Including Synoptic Considerations,” Journal of Atmospheric Research (2010, Vol. 97(4), pp. 513–525)]. An experiment was performed by randomly assigning 52 clouds to be seeded or not. The amount of rain generated was then measured in acre-feet. Here are the data for the unseeded and seeded clouds: Unseeded: 81.2 26.1 95.0 41.1 28.6 21.7 11.5 68.5 345.5 321.2 1202.6 1.0 4.9 163.0 372.4 244.3 47.3 87.0 26.3 24.4 830.1 4.9 36.6 147.8 17.3 29.0 Seeded: 274.7 302.8 242.5 255.0 17.5 115.3 31.4 703.4 334.1 1697.8 118.3 198.6 129.6 274.7 119.0 1656.0 7.7 430.0 40.6 92.4 200.7 32.7 4.1 978.0 489.1 2745.6 Find the sample mean, sample standard deviation, and range of rainfall for a.
