Question

I need help finding the answers for the yellow boxes. Thank you so much :)

A used car dealer says the mean price of a 2008 Honda CR-V is $20,500. A consumer group
believes the acutal mean price is less than that amount. They find that a random sample of 14
similar vehicles has a mean price of $19,850 and a standard deviation of $1084. Is there enough
evidence to support the consumer group's claim at the 0.05 significance level?
