The average cost for a compact sedan is $29,345 in Canada. An SLC student collected data from 500 Kingstonians who own compact sedans and found that they paid an average of $30,142 with a standard deviation of $2,316. Is there a significant difference between the average cost for a compact sedan in Kingston compared to the rest of the country?
