The weight of a bag of industrial salt needs to be monitored using control charts. Several samples were taken where fifteen bags were randomly selected. The average weight of the bag and range were calculated for each sample. Over all the samples, the average weight of the bag was found to be 400 ounces and the average range was found to be 25.50 ounces. What is the lower control limit of the - chart (i. e., x-bar chart)

step-by-step explanation:

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.
