Sound it out: Phonics is an instructional method in which children are taught to connect sounds with letters or groups of letters. A sample of 133 first-graders who were learning English were asked to identify as many letter sounds as possible in a period of one minute. The average number of letter sounds identified was 34.21 with a standard deviation of 23.33. Part: 0/2 Part 1 of 2 (a) Construct a 99.9% confidence interval for the mean number of letter sounds identified in one minute. Round the answers to at least two decimal places. A 99.9% confidence interval for the mean number of letter sounds identified in one minute is <μ<. X S 8 B 19
