What does the central limit theorem tell us about how precision in estimates increases with sample size? for example, with a population of 25 the probability that the sample mean will be more than 0.1 population standard deviations from the population mean is:

Asmall business produces and sells balls. the fixed costs are $20 and each ball costs $4.32 to produce. each ball sells for $8.32. write the equations for the total cost, c, and the revenue, r, then use the graphing method to determine how many balls must be sold to break even.
