6.50 How's it going?: The American National Election Studies (ANES) collects data on voter attitudes and intentions as well as demographic information. In this question we will focus on two variables from the ANES dataset (ANES, 2012). region (levels: Northeast, North Central, South, and West) whether the respondent feels things in this country are generally going in the right direction or things have pretty seriously gotten off on the wrong track To keep calculations simple we will work with a random sample of 500 respondents from the ANES dataset. The distribution of responses are as folows: Right Direction Wrong Track Total Northeast 29 54 83 North Central 44 77 121 South 62 131 193 West 36 67 103 Total 171 329 500 There are TWO parts to this question.

A small study (n=10) is designed to assess if there is an association between smoking in pregnancy and low birth weight. Low birth weight babies are those born less than 5.5 pounds. The following data represent the birth weights, in pounds, of babies born to mothers who reported smoking in pregnancy and those who did not. Mother smoked in pregnancy 5.0 4.2 4.8 3.3 3.9 Mother did not smoke during pregnancy 5.1 4.9 5.3 5.4 4.6 Is there a significant difference in birth weights between mother who smoked during pregnancy and those who did not?

2. QUESTION It has been hypothesized that treatments of plastic used in optic lenses will improve wear. Four different treatments are to be tested. To determine whether any differences in mean wear exist among treatments, 28 castings from a single formulation of the plastic were made and 7 castings were randomly assigned to each of the treatments. Wear was determined by measuring the increase in "haze" after 200 cycles of abrasion (better wear being indicated by smaller increases). The data collected are reported in the accompanying table. Treatment A B 9.16 11.95 11.47 11.35 13.29 15.15 9.54 8.73 12.07 14.75 11.26 10.00 11.97 14.79 13.66 9.75 13.31 15.48 11.18 11.71 12.32 13.47 15.03 12.45 11.78 13.06 14.86 12.38 83.90 98.65 87.00 76.37 11.986 14.093 12.429 10.910
Page 3 The Environmental Protection Agency regulates the amount of lead in tap water. According to EPA regulations, if lead concentrations exceed 15 ppb in more than 8% of customer faucets sampled then the local Water Department must take "additional steps" such as replacing service lines and informing the public. Note: ppb means “parts per billion". Suppose that in a particular city a large number of faucets were tested and lead levels recorded and the 80th percentile was determined to be 16 ppb. Assume that the sample is large enough for the EPA to obtain meaningful results. Must the water department in this city take "additional steps"? Choose the single answer that best describes your conclusion and reasoning. a. Yes; additional steps are required because 80% of the faucets tested have a lead level equal to 16 ppb. b. Yes; additional steps are required because at least 20% of the faucets tested have lead levels higher than 15 ppb. c. Yes; additional steps are required because at…
1. Metal Tags on Penguins and Length of Foraging Trips. Data were collected over a 10-year timespan from a sample of penguins that were randomly given either metal or electronic tags. One variable examined is the length of foraging trips. Longer foraging trips can jeopardize both breeding success and survival of chicks waiting for food. From a sample of 344 foraging trips for metal-tagged penguins, the mean length was 12.70 days. From a sample of 512 foraging trips for electronic-tagged penguins, mean length was 11.60 days. Test whether foraging trips are longer on average among metal-tagged penguins than among electronic-tagged penguins. a. State hypotheses in terms of two means. b. Calculate the sample statistic XM - XE c. An estimate of the standard error for this difference of means is SE-0.2834. Calculate a test statistic to two decimal places. d.

The article "Vehicle-Arrival Characteristics at Urban Uncontrolled Intersections" (V. Rengaraju and V. Rao, Journal of Transportation Engineering, 1995: 317-323) presents data on traffic characteristics at 10 intersections in Madras, India. One characteristic measured was the speeds of the vehicles traveling through the intersections. The accompanying table gives the 15th, 50th, and 85th percentiles of speed (in km/h) for two intersections. Percentile Intersection 15th 50th 85th 27.5 37.5 40.0 в 24.5 26.5 36.0 If a histogram for speeds of vehicles through intersection A were drawn, would it most likely be skewed to the left, skewed to the right, or approximately symmetric? Explain. b. If a histogram for speeds of vehicles through intersection B were drawn, would it most likely be skewed to the left, skewed to the right, or approximately symmetric? Explain. a.
