Assume that last year in a particular state there were 234 children out of 1770 who were diagnosed with Autism Spectrum Disorder. Nationally, 1 out of 88 children are diagnosed with ASD. It is believed that the incident of ASD is more common in that state than nationally. Calculate a 90% confidence interval for the percentage of children in that state diagnosed with ASD.
