Use the following for Questions 1-4. A random sample of baseball players and a random sample of non- baseball players were tested for depth perception. They were asked to align a pointer with a target. The data collected were the distances in millimeters that the pointer was from the target. Smaller distances indicate better depth perception. Data were analyzed with MINITAB with the output shown below. How many total individuals were involved in the study?
Two-shape T for Non-Baseball Players vs. Baseball Players
N Mean StDev Se Mean
Non- Base Ball 6 8.50 3.45 1.4
BaseBall 6 3.33 2.16 0.88
Difference = mu Non-Baseball Players - mu Baseball Players
Estimate for difference: 5.17
99% CI for difference: (1.33, 9.00)
T-Test of difference = 0 (vs not =): T-value = 3.11 P-value + 0.014 DF = 8
What is the value of the two sample t-statistic?
What conclusion do we reach?
What is the difference between the means of the readings for non-baseball players and baseball players?
