1. If research samples 28 college students and wants to compare the sample mean of 12 to
the population mean of 12 that has a standard deviation of 3, what is the standard error for
this situation?

2. The distribution of SAT scores is normal with a mean of 550 and a standard deviation of 120. What SAT score separates the top 10% of the distribution?

7. A student wants to estimate the mean score of all college students for a particular exam. First use the range rule of thumb to make a rough estimate of the standard deviation of those scores. Possible scores range from 800 to 1400. Use technology and the estimated standard deviation to determine the sample size corresponding to a 90​% confidence level and a margin of error of 100 points. What​ isn't quite right with this​ exercise?

Estimating Mean SAT Math Score The SAT is the most widely used college admission exam. (Most community colleges do not require students to take this exam.) The mean SAT math score varies by state and by year, so the value of µ depends on the state and the year. But let’s assume that the shape and spread of the distribution of individual SAT math scores in each state is the same each year. More specifically, assume that individual SAT math...
