Use a 0.05 signicance level to test the claim that the proportion of people over 55 who dream in black and white is greater than the proportion for those under 25. Complete parts (a) through (0) below @* (Round to two decimal places as needed.) Identify the P-value. Pvalue = 0.000 (Round to three decimal places as needed.)
