Researchers studying the effects of diet on growth would like to know if a vegetarian diet affects the height of a child. The researchers randomly selected 10 vegetarian children that were six years old. The average height of the children is 42.5 inches with a standard deviation of 3.3 inches. The average height for all six-year-old children is 45.75 inches. Using confidence intervals, test to determine whether there is overwhelming evidence at a = 0.02 that six-year-old vegetarian children are not the same height as other six-year-old children. Assume the population is normally distributed. Step 1 of 2: Calculate a confidence interval for the average height of six-year-old vegetarian children. Round your answers to two decimal places.
