An experiment was performed to attempt to answer the question of interest posed in Question 12. In the experiment, 48 Israeli college students were randomly assigned to eat in groups of six. Before ordering, half of the groups were told they would each be responsible for individual meal costs and the other half were told that the cost would be split equally among the six people at the table. The cost of meals per person was recorded. Summary statistics are given below: Payment Type Split Individual Bill Sample 24 24 size Sample $37.29 $50.92 mean Sample $12.54 $14.33 st. dev. Suppose a 95% confidence interval for µsplit - Hindividual iS constructed. What is the t* critical value? (Use the conservative estimate of degrees of freedom = smaller sample size - 1). %3D Report your answer to three decimal places.
