1. Suppose we are interested in analyzing how much people spend
on travel during the summer. We know that on average, people spend
$1005 on travel with a population standard deviation of $1740.
Suppose we take a sample of 30 people and we find that the average
spent from that sample is $1850. We are interested in seeing if the
amount spent on travel is increasing. a. What is the standard
error? b. What is the margin of error at...
