The distribution of blood types among white Americans is approximately as follows: type A: 0.36, type B: 0.123, type O: 0.479, and type AB: 0.038 Suppose that we select 2 people at random from this population and observe their blood type. What is the probability that they will both have the same blood type?
In Chapter 10 you study two different types of hypothesis tests: -Claim about a Population Proportion -Claim about a Population Mean An example of each is given below. For each one, state which type of test it is, define the parameter in question, and write the null hypothesis for the test symbolically (use the math palette if necessary for appropriate symbols). (a) A research hospital tries a new antibiotic scrub before surgery to see whether it can lower the rate...
.A sample of 200 individuals are tested for their blood type is given in the first table, and the results are used to test the hypothesized distribution of blood types. The observed results are given in the second table. At the .05 level of significance, is there sufficient evidence to show that the stated distribution is incorrect? Blood Type A B O AB Percent 0.41 0.06 0.41 0.12 Blood Type A B O AB Number 73 17 84 26 (a)...
The age distribution of the Canadian population and the age distribution of a random sample of 455 residents in the Indian community of a village are shown below. Use a 5% level of significance to test the claim that the age distribution of the general Canadian population fits the age distribution of the residents of Red Lake Village. (a) What is the level of significance? State the null and alternate hypotheses O Ho: The distributions are different. H1: The distributions...
A random sample of 1000 voters registered in the state of Montana showed that 490 voted in the last general election. A random sample of 800 voters in the state of Arizona showed that 368 voted in the most recent general election. Do these data indicate that the population percentage of voter turnout in Arizona is lower than that in Montana? 11. Choose the appropriate null and alternate hypotheses. a. Null: The percentage of people who voted in Arizona and...
