1. The raw scores on the standardized reading test are normally distributed so the raw scores can be converted into a distribution of Z scores. If we want to mark the lower 5% of the distribution on the Z distribution, what is the Z value that is the cut-off point for that 5% tail region? (Answer with the exact Z value found from the Z table) 2. What would be the cut-off raw score if we want to mark the...

In the Isolation of Eugenol experiment, whole cloves are placed in a round bottom flask along with water, and the mixture is distilled. The distillate obtained is placed in a separatory funnel, and pentane is added. The contents are then thoroughly mixed, and the pentane layer is collected. a). What is the purpose of separating the pentane layer? b). Can you use ethanol instead of pentane? Explain briefly.
