In a study, there were 447 children out of 32,455 who were diagnosed with Autism Spectrum Disorder. Nationally, about 1 in 85 children are diagnosed with ASD. Is there sufficient data to show that the incidence of ASD is more in the study than nationally? Test at the 5% level. State the hypotheses. Round proportions to two decimal places. Ho: P ? Ha: p? Calculate the sample proportion. Round to four decimal places. p= Calculate the test statistic. Round to three decimal places. Z= Find the p-value. Round to four decimal places. p-value= State your decision. O Since the p-value is less than .05, reject Ho. Since the p-value is greater than .05, reject Ho. Since the p-value is greater than .05, fail to reject Ho. O Since the p-value is less than .05, fail to reject Ho- Interpret the results. O At the 5% level of significance, there is enough evidence to show that the proportion of children in the study with ASD is less than the national proportion. O At the 5% level of significance, there is enough evidence to show that the proportion of children in the study with ASD is not equal to the national proportion.
