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...
