The average age at which adolescent girls reach their adult height is 16 years. Suppose you have a sample of 29 adolescent girls who are developmentally delayed, and who have an average age at which they reached their adult height of 17.8 years and a sample variance of 77.4 years. You want to test the hypothesis that adolescent girls who are developmentally delayed have a different age at which they reached their adult height than all adolescent girls. In order to calculate the t statistic, you first need to calculate the estimated standard error. The estimated standard error SM = (round to four decimals)

Question
The average age at which adolescent girls reach their adult height is 16 years. Suppose
you have a sample of 29 adolescent girls who are developmentally delayed, and who
have an average age at which they reached their adult height of 17.8 years and a
sample variance of 77.4 years. You want to test the hypothesis that adolescent girls
who are developmentally delayed have a different age at which they reached their
adult height than all adolescent girls.
In order to calculate the t statistic, you first need to calculate the estimated standard
error. The estimated standard error SM = (round to four decimals)
