- A study was conducted in the tidal flat at Polka Point, North Stradbroke Island to examine the distribution of the animals that live with the seagrass Sargassum at different distances from the shoreline. Samples of Sargassum were taken at 5, 10, 15 m from the shore and these were examined for amphipods and isopods. The observations are recorded below. Is the distribution of each of the organisms with regards to the shore the same at all three distances? Use the data below to test the hypothesis at the p < 0.05 level. Clearly state the hypotheses and interpret the results. (Note: Find chi-square for each individual column (amphipods and isopods, not the two together) Distance Amphipods Isopods 5 2 7 10 31 14 15 45 22Thirty Asian Utility vehicles were tested for biodiesel fuel efficiency (in km/liter).

- A sample of 20 participants took part in a hearing experiment. Among other things the absolute hearing threshold (in decibels) was measured for each participant. The 20 measurements were as follows. Draw the histogram for these data using an initial class boundary of 16.5, and ending class battery of 41.5 and 5 classes of equal width. Note that you can add or remove classes from the figure label each class with its endpoints.In a fabric manufacturing factory, the quality control process using control charts from SPC.

- A taxi company manager is trying to decide whether the use of radial tires instead of regular belted tires improves fuel economy. Twelve cars were equipped with radial tires and driven over a prescribed test course. Without changing drivers, the same cars were then equipped with regular belted tires and driven once again over the test course. The gasoline consumption, in kilometers per liter, was recorded as follows: (image attached) Can we conclude that cars equipped with radial tires give better fuel economy than those equipped with belted tires? Assume the populations to be normally distributed. Use both p-value and critical value approach.The article “Snow Cover and TemperatureRelationships in North America and Eurasia” (J.Climate and Applied Meteorology, 1983: 460–469) usedstatistical techniques to relate the amount of snow coveron each continent to average continental temperature.Data presented there included the following ten observationson October snow cover for Eurasia during the years1970–1979 (in million km2):6.5 12.0 14.9 10.0 10.7 7.9 21.9 12.5 14.5 9.2What would you report as a representative, or typical,value of October snow cover for this period, and whatprompted your choice?Accumulation of mercury (Hg) in fish is hypothesized to correlate with the fish size.

Of special interest is the study of the number of moose killed by wolves. In the period from 1958 to 1974, there were 296 moose deaths identified as wolf kills. The age distribution of the kills is as follows. Age of Moose in Years Number Killed by Wolves Calf (0.5 yr)1-56-1011-1516-20 1084870682 (a) For each age group, compute the probability that a moose in that age group is killed by a wolf.
