7. ? Travel expenses paid by companies changes when there are rate changes in the daily rate for hotel rooms. The following data gives typical daily rates for hotels in 2022 and 2019. 2022 rates ? 2019 rates $\bar{X}$ ? $265 ? $255 $\sigma$ ? $35 ? $25 n ? 16 ? 10 Is there evidence that the average daily rate is higher in 2022 than 2019.

Step 1
The alternative hypothesis (H1) is that the average daily rate in 2022 is higher than in 2019. H0: μ2022 = μ2019 or μ2022 - μ2019 = 0 H1: μ2022 > μ2019 Show more…

Hotel prices worldwide are projected to increase by 3% next year (Lodging Magazine website, June 15, 2016), but is there a difference between Europe and the U.S.? Suppose we have projected changes in hotel costs for 47 randomly selected major European cities and 53 randomly selected major U.S. cities. These data are provided in the DATAfile IntHotels. a. On the basis of the sample results, can we conclude that the mean change in hotel rates in Europe and the US are different? Develop appropriate null and alternative hypotheses. b. Use α = 0.01. What is your conclusion?

Hotel Rates The average daily rate of U.S. hotels from 2006 through 2009 is approximated by the function $$f(t)=\left\{\begin{array}{ll}0.88 t^{2}+3.21 t+96.75 & \text { if } 0 \leq t<2 \\-5.58 t+117.85 & \text { if2 } \leq t \leq 3\end{array}\right.$$ where $f(t)$ is measured in dollars and $t=0$ corresponds to 2006. a. What was the average daily rate of U.S. hotels in $2006 ?$ In $2007 ?$ In $2008 ?$ b. Sketch the graph of $f$.
