Problem-
The average expenditure per student (based on average daily attendance) for a certain school year was $10,337 with a population standard deviation of $1560. A survey for the next school year of 150 randomly selected students resulted in a sample mean of $10,798. Do these results indicate that the average expenditure has changed? Choose your own level of significance.
Additional information-
This problem related to Basic Statistics and it is about computing the change in the average expenditure on students of a school in two years. The change in average expenditure needs to be noted.
