One factor in the development of tennis elbow, a malady that strikes fear in the hearts of all serious tennis players, is the impact-induced vibration of the racket-and-arm system at ball contact. It is well known that the likelihood of getting tennis elbow depends on various properties of the racket used. Consider the scatter plot of x = racket resonance frequency (Hz) and y = sum of peak-to-peak acceleration (a characteristic of arm vibration, in m/sec/sec) for n = 23 different rackets.† Discuss interesting features of the data and scatter plot.

Flavia wanted to know if the first sample quartile (or Q1) was an unbiased estimator of the first population quartile. She started with a large population of normally distributed grades, the first quartile of which was Q = 70. She then took a random sample of 6 tests and calculated the first quartile of the sample. She replaced those exams and repeated this process a total of 50 times. Her results are summarized in the dot plot below, where each point represents the first sample quartile of a sample of 6 exams. Based on these results, does the first sample quartile appear to be a biased or unbiased estimator of the first population quartile? Track; the first population quartile is 70.

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 22

Q1A) List down the measures of central tendency and measures of dispersion 1) Q1B) The operations manager of a plant that manufactures tires wants to compare the actual inner diameters of two grades of tires, each of which is expected to be 575 millimeters. A sample of five tires of each grade was selected, and the results representing the inner diameters of the tires, ranked from smallest to largest, are as follows. Grade X grade Y 568 570 575 578 584 573 574 575 577 578 requirement. a) for each of the tow grades of tries, compute the mwan, median, and standred deviation. b) which grade of tire providing better quality? explain. c) what would be the effect on your answer in (a) and (b) if the last value for grade Y were 588 insert 578 explain.

Mars, Inc. states that 16% of all milk chocolate M&M’S® produced are green. A group of students took the following samples from a bowl of 500 mixed up M&M’S®. (see attached) What information do we need in order to answer our question or investigate the claim that 16% of milk chocolate M&M’S® produced by Mars, Inc. are green? How can we use the samples of M&M’S® to obtain this information? What value is at the center of the dot plot constructed by using one sample per group? Is it a coincidence that the value is close to/far from the 16% claimed by Mars, Incorporated? Mars, Inc. claimed that 16% of milk chocolate M&M’S® produced are green. Does the information on the dot plot seem to support this claim? Why or why not?
A sample of 10 people ingested a new formulation of a new drug. Six hours later, the concentrations in their bloodstreams, in nanograms per mililiter were as follows: 2.3 1.4 1.8 2.1 1.0 4.1 1.8 2.9 2.5 and 2.7. Construct a dot plot for this sample. Is it reasonable to treat the sample as coming from an approximately normal population? Explain.
A statistical program is recommended. Head movement evaluations are important because individuals, especially those who are disabled, may be able to operate communications aids in this manner. An article reported data on ranges in maximum inclination angles of the head in the clockwise anterior, posterior, right, and left directions for 14 randomly selected subjects. Consider the accompanying data on average anterior maximum inclination angle (AMIA) both in the clockwise direction and in the counterclockwise direction.
