An author argues that more American-born baseball players have birth dates in the months immediately following July 31 because that was the age cutoff date for nonschool baseball leagues. The table below lists months of births for a sample of American-born baseball players and foreign-born baseball players. Using a 0.01 significance level, is there sufficient evidence to warrant rejection of the claim that months of births of baseball players are independent of whether they are born in America? Do the data appear to support the author's claim? Jan. Feb. March April May June July Aug. Sept. Oct. Nov. Dec. Born in America 385 332 365 344 339 316 315 503 419 433 397 368 Foreign Born 101 81 86 83 95 83 59 91 70 99 104 82 ..... Identify the null and alternative hypotheses for this test. O A. Ho: The frequency of births is dependent of the month. H1: The frequency of births is independent of the month. O B. Ho: Months of births of baseball players are independent of where they are born.

Out of 188 men over age 65 years, 70 were still working. 87 out of 202 women over the age of 65 yearswere still working. At a 0.08 level of significance, can you claim the proportion of men and women workingover the age of 65 is the same? a.)State the hypotheses and label the claim. b) Is the test left-tailed, right-tailed, or two-tailed (circle one)?c) What is/are the critical value(s)? Draw a picture. d) What is the P-value and test-statistic?e) Give two reasons for your decision to reject/not reject H0 based on: 1) Test statistic compared to criticalvalue 2) P-value compared to α Then, state the conclusion by relating back to the original claim.
