Questions 24 are based on the following materials. A GT student was asked to nd the weights of two balls. A and B. using a scale with random measurement errors. When the student measured one ball at a time, the weights ofA and B were 3 lbs and 4 lbs. However, if the student measured both balls simultaneously. then the total weight (A+ B) was 6 lbs. The poor student was confused, and decided to measure (A+B) one more time. The new observed weight of (A+B) is still 6 lbs. For your information. the observed weights are summarized in the following table: ____ Second Time In addition. some cutoff values for the t-distribution might be useful below: Question 2 1 pts Based on the method of least squares. what are the estimated weights of balls A and B? Round your answer to the nearest tenth in the format of xx). A A A- ,B=-_
