BREW  This tab contains data on beer for all fifty states plus the District of Columbia.  The       variables are :

BCPC: Beer consumption (in gallons), per capita.

INC: Per capita annual income

MB: total number of microbreweries in the state

TAX: Tax per gallon assessed on beer

FPCT: Proportion of the state’s population that is female

POP: State population in millions

TEMP: Mean state temperature

Calculate the number of microbreweries per million population.  For each numeric variable, calculate mean, median, maximum, minimum. 25th percentile, 75 percentile and standard deviation.  Without sorting, determine Rhode Island’s rank in each category, ranked from highest to lowest.  Report the correlation matrix.  Graph the histogram of beer taxes using bin increments of $0.10 from 0 to $1.30.

SAT  This worksheet contains data concerning average SAT scores for the 50 states and Washington DC including participation rate (% of seniors taking SAT), per pupil expenditure and per capita income. Calculate mean medians, maxima, minima, and standard deviations for each variable.  Report the correlation matrix.

GRADES This worksheet contains grades (attendance, eight quizzes, two mid-terms and a final) for 34 students from an old class.  Attendance is worth 10% of the overall grade and is based purely on the proportion (out of 42) of classes attended. Homework is worth 15% and is based on the average score of eight homework assignments, each of which was worth 10 points.  The remaining 75% will be allocated as follows: 30% to the highest of the three exam grades, 25% to the middle grade, and 20% to the lowest.  Students will receive an additional point added to their average for attending all classes, and an additional point if they turned in all eight homework assignments.  Write a spreadsheet that calculates averages and assigns letter grades based on the following grade distribution:
