The table below shows the number of mothers in each group who did and did not use prenatal vitamins during the three months before pregnancy (periconceptional period).

What is the value of the test statistic for this test? (Please round to two decimal places) What is the p-value associated with this test? (Please round to four decimal places) The result of the hypothesis is: O Since p-value > a we reject the null hypothesis and have sufficient evidence that the proportion of those children who developed autism who had mothers who took prenatal no who bad
