In the state of Missouri, there are 229 eight year olds diagnosed with ASD out of 18,450 eight year oldsevaluated. In the state of Wyoming, there are 47 eight year olds diagnosed with ASD out of 2,202 eight yearolds evaluated. Estimate the difference in proportion of children diagnosed with ASD between Missouri andWyoming. Use a 95% confidence level. Round to four decimal places.With% confidence, it can be concluded that the difference in proportion of childrenanddiagnosed with ASD between Missouri and Wyoming (P₁-P2) is between

According to a report on consumer fraud and identity theft, 24% of all complaints for a year were for identity theft. In that year, Connecticut had 861 complaints of identity theft out of 3484 consumer complaints. Does this data provide enough evidence to show that Connecticut had a higher proportion of identity theft than 24% ? Test at the 10% level. State the hypotheses. Ho: P? O Ha: P ? Calculate the test statistic. Round to four decimal places. p = Calculate the standardized 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 greater than .10, reject Ho. O Since the p-value is less than .10, fail to reject Ho- O Since the p-value is greater than .10, fail to reject Ho. O Since the p-value is less than .10, reject Ho. Interpret the results. O At the 10% level of significance, there is enough evidence to show that the proportion of complaints due to identity theft in Connecticut is…
Construct a 95% confidence interval for p1 - p2 for a survey that finds 30% of 240 males and 41% of 200 females are opposed to the death penalty. Group of answer choices a.(-0.200, -0.021) b.(-1.532, 1.342) c.(-1.324, 1.512) d.(-0.561, 0.651)
Students at a certain college were asked if they have a car. After surveying 501 students, it was found that 20.4% of them have a car. The margin of error was 3.6% with a 95% confidence level. What does this margin of error tell you about the percentage of students at that college who have a car? We can be 95% confident that somewhere between % and % of the students at that college have a car.
In a survey of 2024 adults in a recent year, 709 made a New Year's resolution to eat healthier. Construct 90% and 95% confidence intervals for the population proportion. Interpret the results and compare the widths of the confidence intervals.
Suppose we estimated that 68 percent of Santa Fe students believe that black coffee is disgusting. If we wanted to know the true proportion of the students who share the same view at 99 percent confidence and 4.5 percent margin of error, how many people would we need to sample?
Suppose you calculate a 99% confidence interval of 14.71 to 21.64. Determine the margin of error.
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.
Suppose you calculate a 99% confidence interval of 14.1 to 21.84. Determine the margin of error.
