Meteorologists in texas want to increase the amount of rain delivered by thunderheads by seeding the clouds. without seeding, thunderheads produce, on average, 300 acrefeet. the meteorologists randomly selected 30 clouds which they seeded with silver iodide to test their theory that average acrefeet is more than 300. the sample mean is 370.4 with a sample standard deviation of 300.1. rainfall-oct13 what conclusion can be drawn when the significance level is 0.05? the data does not provided statistical evidence that the average acrefeet from seeded clouds is more than 300. two of the above are correct. we can not draw conclusions based on the p-value because the conditions are not met due to the extreme outliers.
