Ryan would like to create a $95\%$ confidence interval for the average number of goals scored per game (both teams combined) in the National Hockey League last season. His plan is to take a random sample of $40$ of last season’s $1230$ games, record the combined number of goals per game, and use this data to calculate his interval using the formula
$\bar x \pm t^*_{n-1} \dfrac {s_x}{\sqrt n}$
**Which statement about Ryan’s confidence interval is true?**
