n 2008, there were 507 children in Arizona out of 32,601 who were diagnosed with Autism Spectrum Disorder (ASD) ("Autism and developmental," 2008). Find the proportion of ASD in Arizona with a confidence level of 99% by answering the following questions: (iv) Determine error bound of the proportion: Enter value in decimal form rounded to nearest ten-thousandth. Examples of correctly entered answers: 0.0000 0.0010 0.0300 0.6000 0.8147 2.0000 (v) Determine the confidence interval. Enter lower bound value to nearest ten-thousandth, followed by < , followed by "p" for proportion or μ for mean, followed by <, followed by upper bound value to nearest ten-thousandth. No spaces between any characters. Do not use italics. Examples of correctly entered answers: 0.7754
In 2008, there were 507 children in Arizona out of 32,601 who were diagnosed with Autism Spectrum Disorder (ASD) ("Autism and developmental," 2008). Find the proportion of ASD in Arizona with a confidence level of 99% by answering the following questions:
(iv) Determine error bound of the proportion:
Enter value in decimal form rounded to nearest ten-thousandth. Examples of correctly entered answers:
0.0000 0.0010 0.0300 0.6000 0.8147 2.0000
(v) Determine the confidence interval.
Enter lower bound value to nearest ten-thousandth, followed by < , followed by "p" for proportion or μ for mean, followed by <, followed by upper bound value to nearest ten-thousandth. No spaces between any characters. Do not use italics. Examples of correctly entered answers:
0.7754<p<0.7831
13.1224<μ<13.9976
-9.7261<μ<-8.0833
(vi) Using the confidence interval, select the correct description of the result of the survey:
A. We estimate with 95% confidence that the proportion of children in Arizona in 2008 that were diagnosed with Autism Spectrum Disorder (ASD) is between 0.0138 and 0.0174.
B. We estimate with 99% confidence that the true proportion of children in Arizona in 2008 that were diagnosed with Autism Spectrum Disorder (ASD) is between 0.0138 and 0.0174.
C. We estimate with 99% confidence that the population of children in Arizona in 2008 that were diagnosed with Autism Spectrum Disorder (ASD) is between 0.0138 and 0.0174.
D. We estimate with 95% confidence that the true population of children in Arizona in 2008 that were diagnosed with Autism Spectrum Disorder (ASD) is between 0.0138 and 0.0174.
