In D. melanogaster, a homozygous female with mutations for vestigial wings (vg), black body (b) and purple eye color (pr) was mated to a homozygous wild-type male. All the F₁ progeny, both male and female, had normal (wild-type) phenotypes for the three characteristics, indicating that the mutations are autosomal recessive. In a testcross of the F₁ females with males that have vestigial wings, black body and purple eyes, the progeny were of eight different phenotypes reflecting eight different genotypes. The order in which the genes are list below is completely arbitrary.

SPSS.1 A study reveals that older adults work out a little harder when they listen to music. The table below contains the data from two groups of older adults: one group listened to music while walking; the other group did not listen to music. Stride length was measured as an indicator of how hard they were working out (higher numbers = longer stride = working out harder).

A company is using Markov theory to analyse switching between four different foods marketed as slimming aids. These slimming aids claim that with regular use they result in significant weight loss. Individual customers who buy these sliming aids only switch (on average) once every four months. Market research has produced the data shown below for the probability of customers switching between slimming aids. UL20/0468 Page 6 of 9 To 1 slimming aid From slimming aid 1234 1 0.04 0.02 0 0 0.55 0.89 0 0 0.30 0.04 0 0 0.11 0.05 1 2 3 4 Here, for example, there is a probability of 0.11 that a customer switches to slimming aid 4 from slimming aid 2. The current market shares are 9%, 78%, 3% and 10% for aids 1, 2, 3 and 4 respectively. (a) Copy the following table into your answer and fill in the long-run prediction for the market shares for these four slimming aids. Long-run (%, 2dp) Aid 1 Aid 2 Aid 3 Aid 4 (b) The appropriate regulatory authority in the country where these four slimming aids are marketed has been concerned about the claims made for weight loss. As a result of an investigation which they have made they intend to ban sliming aid 2 from the market in six months’ time for making false claims. Giving a clear explanation of your working, copy the following table into your answer and fill in the percentage of the market that will be affected by this ban when it is imposed in six months’ time.

(All answers were generated using 1,000 trials and native Excel functionality.) Galaxy Co. sells virtual reality (VR) goggles, particularly targeting customers who like to play video games. Galaxy procures each pair of goggles for $150 from its supplier and sells each pair of goggles for $300. Monthly demand for the VR goggles is a normal random variable with a mean of 160 units and a standard deviation of 40 units. At the beginning of each month, Galaxy orders enough goggles from its supplier to bring the inventory level up to 140 goggles. If the monthly demand is less than 140, Galaxy pays $20 per pair of goggles that remains in inventory at the end of the month. If the monthly demand exceeds 140, Galaxy sells only the 140 pairs of goggles in stock. Galaxy assigns a shortage cost of $40 for each unit of demand that is unsatisfied to represent a loss-of-goodwill among its customers. Management would like to use a simulation model to analyze this situation.

(a) What is the average monthly profit resulting from its policy of stocking 140 pairs of goggles at the beginning of each month? Round your answer to the nearest dollar. $blank

(c) Use the simulation model to compare the profitability of monthly replenishment levels of 140 and 160 pairs of goggles. Use a 95% confidence interval on the difference between the average profit that each replenishment level generates to make your comparison. Round your answer to the nearest dollar. The average difference between the net profit generated by a replenishment level of 160 versus a replenishment level of 140 is $blank    . It means, that monthly replenishment level of 160 maximizes profitability.

Budget Logistic Service operates a number of delivery vans. Each van is distinguished by its registration number, and characterized by the number of passenger seats and the maximal load weight. Budget Logistic operates various permanent delivery lines among the businesses in the neighborhood. Each line is assigned a unique number. A line has at least two stops: the origin and the destination. For a given line, a sequence of stops may exist between the origin and the destination. These stops also need to be recorded clearly as they will be used for scheduling purposes.That is, we need to be able to retrieve the origin, destination and all in-between stops if any. All stops are identified by street addresses. Some stops are shared by several lines. For each stop on each line, a specific time interval (i.e. waiting time) is prescribed for the driver to wait while the customers are bringing their packages. To avoid confusing customers, the waiting time does not depend on the day of the week or the hour. The management team of Budget Logistic keeps a schedule of lines, which fixes all the departure times (from the origin) of each line, on every day of the week. According to the load expectations, the dispatcher assigns one or more vans to each scheduled line. If no delivery jobs are expected on a certain line at a given time, then no vans are dispatched to depart on that line at that time. For each scheduled departure, the dispatcher records a brief advice to the driver, which is a short text.

Question: Construct the relational schema for the Budget Logistic database, based on the above description. Start an ER model then map it to the relational model. Your relational schema should have an adequate normalization up to Fourth normal form (4NF). For each relation you construct, define the primary key and indicate foreign keys, if any.
