Hi there

Please have and look at this and please help

The management team of a soccer stadium wants to estimate the average amount (in Rand) spent on snacks and cool drinks per spectator. It is known that the amount (in Rand) is normally distributed. A random sample of 40 spectators was selected and the sample mean is R37.93 and the sample standard deviation is R7.

Calculate a 95% confidence interval estimate of the actual average amount spent by a spectator and interpret the results.
