The SAM Educational Consultant needs to address the concern of several parents about the age at which children begin to speak. It is only known that the average age at which a child utters his first word is 13.0 months. Given this query, it is decided to implement a technique that can modify the age at which children begin to speak. The study is carried out in the locality where the Consultant is located and this technique is applied to a random sample of 10 children. The results show that the sample mean age at which the first word is pronounced is 10 months, with a standard deviation of 3.34. What is the probability that the technique that can modify the age at which children begin to speak is less than 10 months?
