The store brought in a total of $3750 that day, and the money made from basketballs alone was $66 more than the money made from volleyballs alone. Let x, y, z be the number of footballs, basketballs, and volleyballs sold respectively. Set up the matrix A that solves Ax = b, where x = and 3750 b = 66 A =

- Use log21=0,log22=1, and log24=2 to estimate log23.Using customer demand data, a company estimates it needs to produce items at a takt time of 38 seconds per item. Based on the operator loading chart shown (as is, without balancing), this process can meet takt time. True or FalseWe estimate the following model for wages for major league baseball players: ln(salary)= β0 +β1years + β2gamesyr + β3frstbase + β4scndbase + β5shrtstop + β6thrdbase + β7outfield + u where ln(salary) = the natural log of a player’s salary years = the player’s years in the major league gamesyr = the player’s average number of games played per year and frstbase, scndbase, shrtstop, thrdbase and outfield are each a dummy variable equal to 1 if the player plays that position on the field (when their team is fielding) and 0 otherwise. These are mutually exclusive dummy variables and there is one omitted fielding position, catcher.

- The owner of a pet store is trying to decide whether to discontinue selling specialty clothes for pets. She suspects that only 10% of the customers buy specialty clothes for their pets and thinks that she might be able to replace the clothes with more interesting and profitable items on the shelves. Before making a final decision she decides to keep track of the total number of customers for a day, and whether they purchase specialty clothes for their pet. a) Assuming the pet store owner is correct in thinking that only 10% of her customers purchase specialty clothes for their pets, how many customers should she expect before someone buys a garment for their pet? b) What is the probability that she does not sell a garment until the 5th customer? c) What is the probability that exactly 4 of the first 10 customers buy specialty clothes for their pet? d) What is the probability that at least 3 of the first 35 customers buy specialty clothes for their pet?…I am having troble interpreting these two tables.Should advertisers worry about people with digital video recorders (DVRs) fast-forwarding through their TV commercials? Recent studies by MillwardBrown and Innerscope Research indicate that when people are fast-forwarding through commercials they are actually still quite engaged and paying attention to the screen to see when the commercials end and when the show they were watching starts again. If a commercial goes by that the viewer has seen before, the impact of the commercial may be equivalent to viewing the commercial at normal speed. One study of DVR viewing behavior is described in the article "Engaging at Any Speed? Commercials Put to the Test."† For each person in a sample of adults, physical responses (such as respiratory rate and heart rate) were recorded while watching commercials at normal speed and while watching commercials at fast-forward speed. These responses were used to calculate an engagement score. Engagement scores ranged from 0 to 100 (higher values indicate…

Emotional stability was measured by a written test for which the higher the score, the greater the emotional stability. Ability to perform in a task group was evaluated by the supervisor. An employee was given a 1 if they were able to perform a task in the group, and 0 if they were unable. Following output gives the results from a logistic regression analysis on the data provided by a sample of 27 employees. (a) what is the estimated logistic regression line? (b) Convert your slope estimate into an estimate for the odds ratio, and interpret the results. (c) Estimate the odds of the being able to perform in a task group for an employee with an emotional stability score of 510.
