In the US, 46.6% of all people have type O blood, 39.6% have type A blood, 10% have type B blood and 3.8% have type AB blood. A researcher wants to see if the distribution of blood type is different for millionaires. The table below shows the results of a random sample of 803 millionaires. What can be concluded at the significant level of ALPHA = 0.01. Round answers to 4 decimal places.1) State the hypotheses: 2) You drew 803 samples, and the observed frequencies are recorded below.

A manufacturing company glues one part to another part during the assembly of its final product. Either too much or too little glue presents a problem. It is important for the pressure of the glue nozzle (pounds per square inch) to be set correctly because it affects the amount of glue (ounces) that is applied. Ten applications are sampled and the following information collected: SSXX = 129.6 SSYY = 2.345 SSXY = 16.6 X bar = 25.2 Y bar = 2.05 What is the estimated y intercept?
5. The ABC University wants to know the proportion of its football fans travel to away games in the same state. The university took a random sample of 2000 of its football fans and found that 500 of them travel to away games in the state. • Identify the population for this situation. What is the parameter? What is the sample? • Identify the sample statistic. Can the university estimate the population proportion based on the sample? Explain your answer.
