Question

Question 12 4 pts A study is done to look at the cost of a hotel room in Paris and a hotel room in London. The mean cost in Paris was $534.50 per night and in London $369.50. The 95% confidence interval for cost in Paris is ($437, $632) and the 95% confidence interval for the cost in London is ($335, $404). Which of the following statements is correct? Since the intervals overlap we cannot conclude which city has higher hotel prices. We are 95% confident that the mean cost in Paris was higher because the entire confidence interval is greater than the confidence interval for London. We are 95% confident that the mean cost in Paris is higher because the mean for Paris is greater than the mean for London. There is not enough information to make a statement comparing the cost of hotel rooms in Paris and London.
