Harwood and Naylor (1969) wondered whether visual memory changes with age. A standardized test shows that when young adults (mean age 24 years) have learned to recognize 20 line drawings of common objects, they recognize about 75% of these in a surprise test four weeks later. Harwood and Naylor conducted the same experiment with a random sample of older adults from Montreal, a second random sample of older adults from Maberly, and a third random sample of older adults from Aylmer. The researchers recorded the percentage of recognized drawings (on the surprise test) for each older participant. The data for this question is below. Use this data to answer the following question: compute the proportion of the scores from aylmer that exceed 75. please give the answer to 5 decimal places. 83 63 59 63 55 65 66 60 80 69 65 68 87 69 70 89 68 77 82 106 76 63 50 47 80 69 71 89 72 56 73 76 70 76 79
