1. A manufacturer of electric irons produces these items in two plants. Both plants have thesame suppliers of small parts. A saving can be made by purchasing thermostats for plant B froma local supplier. A single lot was purchased from the local supplier, and a test was conductedto see whether these new thermostats were as accurate as the old. The thermostats weretested on tile irons on the 550 °F setting, and the actual temperatures were read to the nearest0.1 °F with a thermocouple. The data are as follows:New Supplier (°F)530.3 559.3 549.4 544.0 551.7549.9 556.9 536.7 558.8 538.8559.1 555.0 538.6 551.1 565.4550.0 554.9 554.7 536.1 569.1Old Supplier (°F)559.7 534.7 554.8 545.0 544.6550.7 563.1 551.1 553.8 538.8554.5555.0566.3543.3554.9538.0564.6553.0 538.4 548.3 552.9 535.1544.8 558.4 548.7 560.3a. Can we conclude at the 0.01 level of significance that the new supplier performs betterthan the old supplier? Assume the populations to be approximately normal with equalvariances.b. Also, show P-value.

Question 1 Select one answer. 10 points Weight of a rock: In a geology course, students are learning to use a balance scale to accurately weigh rocks. One student plans to weigh a rock 20 times and then calculate the average of the 20 measurements to estimate her rock's true weight. A second student plans to weigh a rock 5 times and calculate the average of the 5 measurements to estimate his rock's true weight. Let’s say that the student who collected 20 weight measurements came up with a mean weight of 27.1 g with a standard deviation of 2.3 grams. The critical T-value for a 95% (one-sample) confidence interval with df = 19 is 2.09. Which of the following is the resulting 95% confidence interval? (25.0, 29.2) (26.0, 28.2) (26.6, 27.6)

Which test should I use for this problem: A fisheries biologist stocks three different species of sunfish into a pond at an equal rate (500 individuals of each species). She is interested in determining whether catch rates of those fish by anglers differ between the three species. Any person who fishes the pond during the month of June keeps a record of how many fish they caught by each species. Each fish caught is removed from the population (i.e., harvested). Across the entire month, 100 bluegill, 75 green sunfish, and 75 redear sunfish were caught.

Rivers in North Carolina contain small concentrations of mercury that can accumulate in fish over their lifetimes. The concentration of mercury in fish tissue can be obtained by catching fish and sending samples to a lab for analysis. A study was conducted on fish from the Waccamaw and Lumber Rivers to investigate mercury levels in tissues of largemouth bass. At several stations along each river a group of fish were caught, weighed and measured; in addition a filet from each fish was sent to a lab so that the tissue concentration of mercury could be determined. In all, 171 fish were caught at 15 different research stations along the Waccamaw and Lumber Rivers. Data from fish caught at one of these stations is shown in the followinng table: length weight 1616 47.0 48.7 1862 2855 55.7 45.2 1199 1320 44.7 1225 43.8 870 38.5 1455 45.8 1220 44.0 1033 40.4 Compute the correlation between length and weight for these fish.

Researchers who are trying a new shampoo formula plan to compare the condition of hair for people who use the new formula with the condition of hair for people who use the existing formula. Twelve volunteers have tried the shampoo and so will serve as our population. Information on those volunteers (numbered 1 to 12) is presented in the table before. Number 1 2 3 4 6. 7 8. 9 10 11 12 Gender Male Female Male Female Female Male Male Female Male Female Male Female Age 21 20 47 60 62 61 58 44 44 24 23 46 a) Researchers want to conduct an experiment to compare the two formulas. They believe response is affected by age but not gender. Design and carry out a stratified sample of this population. There should be 6 people in the sample.
