It is hypothesized that when homing pigeons are disoriented in a certain manner that they will exhibit no preference for any angular direction measured in degrees of flight after takeoff. One notes that takeoff direction measured in angles should be uniformly distributed among all 360° if this were the case. To test this, 120 pigeons are disoriented, let loose, and the direction of flight of each is recorded; the resulting data follows. Direction 0° - 45° 46° 90° 91° - 135° 136° 180° 181° - 225° 226° - 270° 271° - 315° [Frequency 12 17 13 20 17 16 15 316° - 10 - 360° State the relevant null hypothesis necessary to test the claim and then conduct a hypothesis test at signifi- cance level a = 0.10 to see if data supports the hypothesis. [Hint: consider the implications of the uniform distribution on the null hypothesis and look at the number of angular ranges which the birds may fly in.]

Alligators have shown the ability to determine the direction of an airborne sound. But can they locate underwater sounds? This was the subject of a study. Alligators were monitored for movement toward a sound produced from a submerged diving bell. Movements within a 180° arc of the direction toward the sound were scored as movements toward the sound; all movements in other directions were scored as movements away from the sound. Consequently, the researchers assumed that the proportion of movements toward the sound expected by chance is 180°/360° = 0.5. In a sample of n= 50 alligators, 29 moved toward the underwater sound. Complete parts a through e below. a. Give the null and alternative hypotheses for testing whether the true proportion of alligators that move toward the underwater sound is higher than expected by chance. Let p be the true proportion of alligators that move toward the underwater sound. Choose the correct answer below. O A. Ho: p>0.50 vs. Ha: p= 0.50. O B. Ho: p= 0.50…

A company that manufactures golf balls produces a new type of ball that is supposed to travel significantly farther than the company’s previous golf ball. To determine this, 40 new-style golf balls and 40 original-style golf balls are randomly selected from the company’s production line on a specific day. The balls are then placed in a bag and shaken. A golf pro then selects a ball and hits it using a driver. The distance the ball travels is then measured. The bag is shaken again, and the golf pro selects another ball and hits it with the same driver. He continues this procedure until all 80 of the golf balls are hit. Which of the following is a benefit of having replication in the experiment? A)Repeating the experiment will allow the company to compare the distances traveled by the new type of golf ball from both experiments. B)Having a large number of each type of golf ball will allow for a good comparison of the differences in distances traveled for the two types of balls.…

The next four questions (29 to 32) refer to the following: To most Canadians, earthquakes are viewed as rare occurrences, but they are actually quite common. In just one month in 2001, Natural Resources Canada recorded 215 earthquakes that affected Canada from B.C. to Nunavut to Newfoundland. We would like to determine whether there is a linear relationship between the location of an earth- quake X (measured in degrees latitude north of the equator) and the magnitude of the earthquake Y (measured on the Richter scale). The explanatory and response variables are measured for a sample of 13 earthquakes. The equation of the least squares regression line is ŷ = -3.05+ 0.10x. The ANOVA table is showm below: ге Source of Variation df Sum of Squares Mean Square F Regression Error Total 1.40 25.10

Consider the task of clustering Walmart customers into segments based on purchase behaviours. Suppose that the x-coordinate represents money spent on vegetables (in dollars) and the y-coordinate represents money spent on candies (in dollars). The store wants to cluster customers into "healthy" cluster and an "unhealthy" cluster.Which distance metric is not a good choice in this case? Euclidean distance? Cosine distance? Correlation distance? All the same?
