A researcher wishes to see if the proportion of workers for different types of jobs have changed during the past 10 years. The time category will be either now or ten years ago. The type of job classifications are services, manufacturing, government or other. Assume the data result in a test statistic of 10.98 and Table A-4 will be used to determine the p-value. The p-value would be greater than nothing but less than nothing (Answer as a decimal proportion rounded to three digits beyond the decimal as needed.)
