Over a period of many months, a particular 5 year old boy's play activity was observed. The length of time spent in each episode of play with toys was recorded. The paper "A Temporal Analysis of Free Toy Play and Distractibility in Young Children" (Journal of Experimental Child Psychology, 1991,pages 41-69) reported the accompanying data on the play-episode lengths. What is the probability that the play time was less than 75 seconds ? Round to three decimal places. Length of Time Spent in play- Frequency episode (seconds) 0 - less than 5 54 5 - less than 10 44 10 - less than 15 28 15 - less than 20 21 20 - less than 40 31 40 - less than 60 15 Show Transcribed Text Macmillan Learning Incorrect 698'0 15 - less than 20 20 - less than 40 10- less than 15 90 - less than 120 60 - less than 90 120- less than 180 40 - less than 60
