The alternatives to a Chi squared test.

Is there an alternative test to the chi squared test? What if my results give an expected frequency below 5, which stats book states that these should be treated with caution? Is there a more appropriate stat test which would be more accurate in working out the significance of the results?

Confidence interval

I would like you to check the first problem, and provide an answer( including values for Standard deviation,Mean,and Sample) #1. Construct a 95% confidence interval for the population mean. Assume the population has a normal distribution. In a random sample of 26 computers, the mean repair cost was $174, with a standard deviation of $37.00. My Answer; N=26, X=174, S=37 (159.06,188.94) I am having trouble with part two; Suppose you did some research on repair costs for computers and found the standard deviation is 37. Use the normal distribution to construct a 95% confidence interval for the mean. Compare the results.
