A psychologist researching new communication methods believes that is unusual for teenagers to send less than 275 texts each day. Assume that the daily number of texts sent by teenagers follows an unknown distribution with a mean of 300 texts and a standard deviation of 59 texts. The psychologist randomly selects 45 teenagers and records the number of texts they send on a particular day. Use a calculator to find the probability that the sample mean is less than 275 texts. Round your answer to three decimal places.
