Statement (i) correctly describes the null and alternate hypotheses for a goodness-of-fit test. Statement (ii) correctly describes the calculation of degrees of freedom for the test. Statement (iii) is incorrect because large differences between observed and expected frequencies suggest rejecting H0, not accepting it.
