Suppose that a Restaurant chain specialized with pasta having three branches in aparticular geographic location would like to evaluate the service at this restaurant. Theresearcher for the restaurant hires 18 investigators (evaluator) with varied experiences infood- service evaluations. After the initial consultations, the 15 investigators are stratifiedinto five blocks of three-based on food service evaluation experience- so that three mostexperience evaluators are placed in block 1, the next three most experienced evaluatorsare placed in block 2, and so on. Within each of the five homogeneous blocks, the threeevaluators are then randomly assigned to evaluate the service at a particular restaurantusing a rating scale from 0 (low) to 20 (high).

Each term (3 months) the current group of economics students completed a questionnaire as to how much they would spend on new purchases compared to how much they would save/pay off bills, if they suddenly and unexpectedly received a check for $1,000. The average MPC is shown in the table below. Month in which student poll was taken Average of students’ responses as MPC March 0.41 June 0.30 September 0.22 December 0.56 What do these MPC’s imply about the students’ thinking over the course of the year? (Enter response here.) What is likely happening in the economy during the same period of time?
A group of participants was surveyed and the information collected shown in the partially completed contingency table below regarding the site of skin cancer. Firstly, calculate the missing values. Melanoma Other Total Head U 43 X Trunk 52 V 98 Extremities 142 112 Y Total 229 W Z Now, using the completed contingency table, select the statements from the following list that are true. Note: a statement is true only if the value you calculated from the completed contingency table, when rounded to the same number of decimal places as in the statement, is the same as the value in the statement. 18.1% of skin cancers appear on the head 71.4% of skin cancers were melanomas or appeared on the head Given the skin cancer is something other than melanoma, the probability it is not on the extremities is 0.443 Of skin cancers appearing on the trunk, 46.9% are not melanomas
