Based on an indication that mean daily car rental rates may be higher for Helsinki than for Luxembourg, a survey of eight car rental companies in Helsinki is taken and the sample mean car rental rate is €47, with a standard deviation of €3. Further, suppose a survey of nine car rental companies in Luxembourg results in a sample mean of €44 and a standard deviation of €3. Use  0.05 to test to determine whether the average daily car rental rates in Helsinki are significantly higher than those in Luxembourg. Assume car rental rates are normally distributed and the population variances are equal.
