In the 10 years since the new stadium opened, the stadium has brought in far more money for taxpayers than the benefit given to the Cowboys for moving to Arlington, ASRS of 1250 Dallas adults were asked and only 76 said they still support the Mayor's decision.

A) Find the appropriate critical value for the problem

b) What is the margin of error?

c) Construct a 90% confidence interval to estimate the true proportion of residents who still

support the Mayor's decision. Show your work.

d) Is it Plausible that the true proportion is .05?

Questions 9-10. use the table of educational expenditures to answer the questions. k-12 education expenditures population indiana $9.97 billion 6.6 million illinois $28.54 billion 12.9 million kentucky $6.58 billion 4.4 million michigan $16.85 billion 9.9 million ohio $20.23 billion 11.6million 9. if the amount of k-12 education expenses in indiana were proportional to those in ohio, what would have been the expected value of k-12 expenditures in indiana? (give the answer in billions rounded to the nearest hundredth) 10. use the value of k-12 education expenditures in michigan as a proportion of the population in michigan to estimate what the value of k-12 education expenses would be in illinois. a) find the expected value of k-12 expenditures in illinois if illinois were proportional to michigan.
