A report provided the following information on the sex of smartphone users for representative samples of young people ages 15 to 24 in several different countries. Percent Female Percent Male United States 54% 46% Spain 37% 63% Italy 37% 63% India 22% 78% (a) Suppose the sample sizes were 1,000 for the United States and for India and 500 for Spain and Italy. Complete the following two-way table by entering the observed counts. Female Male United States 540 460 Spain 185 315 Italy 185 315 India 220 780 (b) Carry out a hypothesis test to determine if there is convincing evidence that the sex proportions are not the same for all four countries. Use a significance level of 0.05. Calculate the test statistic. (Round your answer to two decimal places.) Use technology or SALT to calculate the P-value. (Round your answer to four decimal places.) P-value =
