How many observations are below the mode?Consider that Roane county, which calculated that the average firm size (in terms of number of employees) is 150 with a median size of 50, while Anderson county calculated an average and median size of 230 and 255 respectively. Officials from both counties are asking their state legislatures for additional funds to accommodate their growing business size. Do you support their requests, why or why not? Also, are there any additional statistics you might ask for and why?The Los Angeles City Controller's office calculated that in 2013, the city employed 4703047030 full‑time employees and 1014210142 part‑time employees. Assume that an outside advocacy group had been lobbying the Mayor's office to convert part‑time workers into full‑time workers throughout 2014. The Controller's office makes its calculations annually. Suppose that the outside advocacy group wanted to know the proportion of city employees (excluding per‑event employees) who are full‑time employees ?p in June 2014 to gauge if their lobbying efforts had been effective. Suppose that the group surveyed a random sample of 1000 city employees (excluding per‑event employees) in June 2014 and found that 845845 were full‑time employees and 155155 were part‑time employees. If the advocacy group planned to use a one‑sample z-z-test for a proportion to test their lobbying eforts, the appropriate null hypothesis would be and the appropriate alternative hypothesis would be Assume…
