At a Midwestern hospital there were a total of 932 births in 20 consecutive weeks. Of these births, 216 occurred on weekends.26 Do these data reveal more than chance deviation from random timing of the births? Consider a goodness of fit test with two categories of births -weekday and weekend -using a non directional alternative.
(a) What is the value of the x2 test statistic?
(b) In the context of this study, state the null and alternative hypotheses.
(c) The P-value for the test is 0.0003. If a = 0.05, what is your conclusion regarding the hypotheses in (b)?
