A chi-square goodness of fit test is used to test whether a 0-9 spinner is "fair" (i.e., the outcomes are all equally likely). The spinner is spun 100 times, and the results are recorded. Which member of the chi-square family of curves is used? (a) x2(8) (b) x²(9) (c) x²(10) (d) x²(99) (e) None of the above
