Suppose we select an SRS of size n = 100 from a large population having proportion of successes. Let p-hat be the proportion of successes in the sample. For which value of p would it be safe to use the Normal approximation to the sampling distribution of p-hat? (a) 0.01 (b) 0.09 (c) 0.85 (d) 0.975 (e) 0.999

large crystals result from very slow cooling.

evaporation of water: this would produce an evaporite which is a sedimentary rock. like a salt pan in a desert. not possible to have volcanic rocks originate this way.

crystalization in molten earth: slow cooling over time. (hundreds to millions of years)

crystalization at earth's surface: this results in fast cooling. (a few hours to a few months or years)

crystalization from cooling off hot water: that would be a hydrothermal deposit. while associated with volcanics they are not volcanic rocks themselves and usually occur fairly rapidly.

i believe your answer is a

hi there!

1. define: accuracy

a) how close a measured value is to the actual (true) value.

hope this : )
