Twenty sculptors were asked to produce molds of a model using a different medium for each one. The options are: having the model present at the session, using a photograph and seeing the model, but having to create the sculpture from memory. The sculptor then rated the difficulty of creating each piece of artwork (1=easy; 10 = difficult). The data is provided below: Subject Model Present Photo Memory 1 9 5 5 2 3 9 6 3 6 8 9 4 1 6 10 5 5 7 7 6 9 4 1 7 8 8 10 8 6 9 4 9 8 3 8 10 1 8 10 11 8 5 10 12 8 7 5 13 6 10 3 14 9 2 7 15 5 8 9 16 1 6 8 17 7 4 7 18 10 9 1 19 3 6 10 20 10 10 10 1.

In this question, the real numbers in your answers should be given with three significant digits of accuracy after the decimal point. The public health authorities of a small town have divided the population into three categories: covid- negative, covid-positive, and hospitalised. After performing regular, extensive tests, they have observed that in each successive week: Among those who are negative, 95% remain so, 4% become positive, and 1% need to be hospitalised. • Among those who are positive, 75% recover and become negative, 20% stay positive, and 5% need to be hospitalised. Among those who are hospitalised, 60% recover and become negative, 30% are released from hospital but remain positive, and 10% remain hospitalised. (a) After representing the population in a given week as a column vector v = [n; p; h], where n, P, and h represent the number of people in the population who are negative, positive, and hospitalised respectively, write down a matrix M for which [n', p', h'] = M[n;…

Studies have found that people find symmetrical faces more attractive than faces that are not symmetrical. To test this theory, a psychiatrist selected a random sample of people and showed them pictures of three different faces: a face that is perfectly symmetrical, a face that is slightly asymmetrical, and a face that is highly asymmetrical. She then asked them to rate the three faces in terms of their attractiveness on a scale from 1 to 7, with 7 being the most attractive. Test the null hypothesis that attractiveness does not differ with facial symmetry.
(b) Disk drive substrates may affect the amplitude of the signal obtained during readback. A manufacturer compares four substrates: aluminum (A), nickel- plated aluminum (B), and two types of glass (C and D). Sixteen disk drives will be made, four using each of the substrates. It is felt that operator, machine, and day of production may have an effect on the drives, so these three effects were blocked. The design and responses (in microvolts ×10–2) are given in the Table Q2(b) (data from Nelson 1993, Greek letters indicate day): Table Q2(b) Operator 3 Machine 1 4 Cy = 11 Aß = 5 B8 = 9 BB = 8 Dy = 4 Ca = 9 1 Αα8 D8 = 2 Cô = 7 DB = 3 By = 4 2 Βα=2 Ay = 7 CB = 9 3 4 Da = 5 Að = 3 Construct an ANOVA table from this experiment at a 0.05 level of significance. Identify whether the four substrates really have an effect on the drives.
