The Department of Statistics Malaysia (DOSM) conducted another study on the monthly gross income (in RM) in Malaysia for 2017. Another four states are selected and the data obtained are shown in Table 2. The Boxplot of the data is given in Figure 1.

Of U.S. residents traveling overseas, 47% were women and 53% were men. A random sample of 500 travelers on a large airline revealed that of those 500, 263 were women. Does this differ from the national average at the 0.05 level of significance?
An article in the newspaper claims that 60% of registered drivers have the organ donor designation on their driver's license. A researcher at a hospital decides to investigate this claim. The researcher selects a random sample of 50 registered drivers and finds that 44.0% have the organ donor designation on their driver's license. Do the data provide convincing evidence at the ?α = 0.05 level that fewer than 60% of registered drivers have the organ donor designation on their license?
