Find the test statistic used for the following hypothesis test.  For H 0 : σ = 63  vs H A : σ ≠ 63, find the test statistic needed for a sample size of 29 and a sample standard deviation of s = 72. Round to three decimal places

Use the given minimum and maximum data entries, and the number of classes, to find the class width, the lower class limits, and the upper class limits. minimum = 7, maximum =92, 7 classes The class width is (Type a whole number.) Use the minimum as the first lower class limit, and then find the remaining lower class limits. The lower class limits are (Type a whole number. Use a comma to separate answers as needed.) The upper class limits are (Type a whole number. Use a comma to separate answers as needed.) Enter your answer in each of the answer boxes.

The value y (in 1982–1984 dollars) of each dollar paid by consumers in each of the years from 1994 through 2008 in a country is represented by the ordered pairs. (1994, 0.675)         (1995, 0.654) (1996, 0.643)         (1997, 0.618) (1998, 0.611)         (1999, 0.599) (2000, 0.585)         (2001, 0.562) (2002, 0.559)         (2003, 0.539) (2004, 0.529)         (2005, 0.513) (2006, 0.493)         (2007, 0.482) (2008, 0.462)          (b) Use the regression feature of the spreadsheet software program to find a linear model for the data. (Let trepresent time. Round your numerical values to four decimal places.) y =   (c) Use the model to predict the value (in 1982–1984 dollars) of 1 dollar paid by consumers in 2010 and in 2011. (Round your answers to two decimal places.)
