Explanation Given: The data of the average U.S. prices per gallon of both regular gasoline and diesel fuel from the year 2003 through 2012 is shown below: Year Cost of regular gasoline Cost of Diesel Fuel 2003 $1.49 $1.48 2004 $1.99 $2.21 2005 $2.34 $2.70 2006 $2.18 $2.51 2007 $3.01 $3.30 2008 $2.45 $3.09 2009 $2.68 $2.81 2010 $2.76 $3.07 2011 $3.37 $3.89 2012 $3.41 $4.01 Procedure used: “Step by step procedure for constructing the double bar graph: 1. The vertical line and horizontal lines called axes are drawn and labeled. 2. Different categories are placed along the horizontal axis. 3. An appropriate scale is placed along the vertical axis. 4. The double vertical barsare drawn corresponding to each category based on the first group frequency and second group frequency.” 1. On the horizontal axis Year is taken. 2. On the vertical axis the scale for Cost per gallon is taken. Note that, the cost of regular gasoline ranges from $ 1

Show that if f is uniformly continuous on [a, b] and uniformly continuous on D (where D is either [b, c] or [b, 00)), then f is uniformly continuous on [a, b]U D. 7. Show that f(x)=√x is uniformly continuous on [1, 00). Use Exercise 6 to conclude that f is uniformly continuous on [0, ∞). 8. Show that if D is bounded and f is uniformly continuous on D, then fis bounded on D. 9. Let f and g be uniformly continuous on D. Show that f+g is uniformly continuous on D. Show, by example, that fg need not be uniformly con- tinuous on D. 10. Complete the proof of Theorem 4.7. 11.

3. Explain why the following statements are not correct. a. "With my methodological approach, I can reduce the Type I error with the given sample information without changing the Type II error." b. "I have already decided how much of the Type I error I am going to allow. A bigger sample will not change either the Type I or Type II error." C. "I can reduce the Type II error by making it difficult to reject the null hypothesis." d. "By making it easy to reject the null hypothesis, I am reducing the Type I error."
