There are 507 children in Arizona out of 32,601 who were diagnosed with a disorder. Nationally 1 in 88 children are diagnosed with ASD . Is there enough data to show that the incident of ASD is more in Arizona than nationally? I should be testing this at the 1% level. Can someone please assist with how I should be answering the below questions
What is the null hypothesis
What is the level of significance being used
what is the test statistic
what is the p-value corresponding to test statistic.
looking at p-value and ? value, which is the correct decision to make for this hypothesis test?
