Entrepreneurship researchers are interested in the relationship between entrepreneurial behaviour of firms, such as innovation or new business venturing, and performance indicators, such as sales growth or profitability.
A burglar plans his crimes so carefully that the lengths of the burglary are uniformly distributed between 50.0 and 52.0 minutes. Find the probability that a given burglary runs between 51.0 and 51.5 minutes.

A random sample of 49 employees took a computer literacy test. The sample resulted in a mean score of 75 with a standard deviation of 21. Estimate the standard error of the mean.
The clinic estimates that the true population standard deviation is around $2,100. If the confidence level is 95%, find the required sample size in order to meet the desired accuracy.
What is the minimum sample size you should use to assure that your estimate of will be within the required margin of error around the population p?
