34. Psychologists have found that twins, in their early years, tend to have lower IQs and pick up language more slowly than non-twins. The slower intellectual growth of most twins may be caused by benign parental neglect. Suppose it is desired to estimate the mean attention time given to twins per week by their parents. A random sample of 43 sets of 2 1/2 year-old twin boys is taken, and at the end of I week, the attention time given to each pair is recorded. The average amount of time was 20.848 hours with a standard deviation of 13.4138 hours. Construct a 95% confidence interval for the mean attention time given to all sets of 2 1/2 year-old twin boys by their parents per week. Interpret the interval in the context of the problem.
