In the state of Iowa, there are 252 eight-year-olds diagnosed with ASD (Autism Spectrum Disorder) out of 18,937 evaluated. In Indiana, there are 41 eight-year-olds diagnosed with ASD out of 2,409 evaluated. This information is used to estimate the difference in the proportion of children diagnosed with ASD between Iowa and Indiana. A 95% confidence level is used for the estimation, and the final answer should be rounded to four decimal places.The text box placeholders are for inputting values:- The first box is for the confidence level percentage (95%).- The second and third boxes are for the lower and upper bounds of the confidence interval of the difference in proportion (p₁ - p₂) between the two states. This information can help understand the statistical analysis used to compare the rates of ASD diagnoses in different populations.

You want to estimate the average difference in the number of complaints filed by women at work and the number of complaints filed by men at work. You took an SRS of 7 businesses and collected the following data for number of complaints in a year: men 1 3 2 4 6 3 5 women 8 7 6 3 5 12 15 Create a 90% confidence interval for the average difference in the number of complaints filed by women at work and the number of complaints filed by men at work (in a year). You must do this using table C. If this is a 2 sample interval, be sure to specify who is population 1 and who is population 2. If this is a matched pairs interval, be sure to state the order you subtracted your data. Once you create your interval, give a sentence explaining the meaning of the interval (what the numbers in the interval mean, NOT the meaning of 95%) in context of this problem. Round to any appropriate number of decimals.
