Researchers studying the effect of diet on growth would like to know if a vegetarian diet affects the height of a child. Twelve students are randomly selected that are all 6-years old. The average height of these kids is 42.5 inches with a standard deviation of 3.8 inches. The average height of all 6-year old kids is found to be 45.75 inches. Conduct a hypothesis test to determine if there is overwhelming evidence at alpha = .05 that 6-year old vegetarian kids are not the same height as other six year-old kids.

  • A. alpha = .05, 1.96 , -3.0

  • B. 2 tail, +/- 2.201, Reject Ho

  • C. 2.33, alpha = .05, 1.645

  • D. 1 tail, 1.645, 1.414

  • E. 2 tail, 2.052, 2.963
