Yvon Hopps ran an experiment to determine the optimum power and time settings for microwave popcorn. His goal wasto find a combination of power and time that would deliver high-quality popcorn with less than 9% of the kernels leftun-popped, on average. After experimenting with several bags, he determined that power 9 at 4 minutes was the bestcombination. To be sure that the method was successful, he popped 8 more bags of popcorn (selected at random) atthis setting. All were of high quality, with the following percentages of uncooked popcorn: 8.4, 11.4, 8.7, 8.3, 4.6, 2.4,3.2, 5.6. Does the 95% confidence interval suggest that he met his goal of an average of no more than 9%uncooked kernels? Explain.The 95% confidence interval for the true mean percentage of unpopped kernels is (%,%).(Round to two decimal places as needed. Use ascending order.)ST

Method: By Using the confidence interval estimation

The Widington College program is considering buying a Scanner machine among 5 (five) types, namely the SC1, SC2, SC3, SC4 and SC5 types, where each type has different efficiency in terms of the speed of the number of pages (sheets) scanned in one minute. Six staff members conducted an experiment to run each type of scanner. The following data shows the number of scanned pages (sheets) that can be produced in one minute according to the type of copier, 1 trial, and according to the staff assigned to run each type of scanner: SC 1 SC 2 SC 3 SC 4 SC 5 Staff 1 60 50 63 60 64 Staff 2 56 55 65 58 60 Staff 3 54 56 65 56 58 Staff 4 56 57 67 65 60 Staff 5 54 56 65 60 60 Staff 6 55 52 58 60 55 Some of the results of the calculation of the sum of squares (sum-square) and the average squared (mean square) required for the ANOVA test are provided in the following table: Source of Variation SS Df MS F stat F Table Scanner Machine 333.3 ..... ..... ..... .....

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.

An educational psychologist is examining response times to an on-screen stimulus. The researcher believes there might be a weak effect from age, but expects a more pronounced effect for different color contrasts. She decides to examine a black on white (B/W) combination compared to 2 alternatives: red on white (R/W) and yellow on blue (Y/B). Here is the data for response times (in milliseconds): B/W R/W Y/B 16–17 213025351592110 201931234320716 42023218442534 18–19 1433242512161720 3936173735154719 2836312336234531 20–21 2718273916212423 2926412920312719 3643173928264043 Using MS Excel, conduct a 2-way ANOVA with α=0.05α=0.05.

A Biology 20 class wanted to investigate the endurance of fellow students related to the activity of muscle cells. A muscle is said to be fatigued when it is unable to maintain a certain level of performance. The students designed an experiment that used the number of repetitions of a muscle group to indicate the level of performance. Procedure: Each individual used the apparatus diagrammed above to perform three trials. First a 250 gram load was used, then 500 grams, and lastly a 1000 gram load was used. A 1 litre soft drink bottle was filled with the appropriate mass of water. (1 mL of water = 1 gram). The subject was instructed to raise and lower each mass rapidly -- about twice a second. The trial was considered finished if the subject could not raise the weight 3 cm or was unable to maintain a rate of 2 lifts per second. Between trials the subject had a 1 minute rest. During this time the arm of the subject could be massaged. I Questions: (a) What problem were the Biology 20 class…
_) Jane bakes sourdough loaves, which are full of gluten. Unfortunately, John is allergic to gluten and wants to bake gluten-free loaves. John does not have their own “starter” (a mix of yeast, flour, and water that makes a loaf rise in the oven). Jane's starter is 50g of water and 50g of flour with gluten, and a microscopic amount of yeast that we will ignore. Jane gives John 50g of her starter. For John's first loaf, they replace the missing half of their starter with 25 g of gluten-free flour and 25g of water. This means their starter is now 25g of gluten-free flour, 25g of flour with gluten, and 50g of water. Once the yeast in this starter is fully activated, John is ready to make their first loaf. To bake the loaf they mix 50 g (half) of the starter with 225g of gluten-free flour and 225g of water, meaning the loaf is always
Josh ran an experiment to test optimum power and time settings for microwave popcorn. His goal was to deliver popcorn with fewer than 11% of the kernels left unpopped, on average. He determined that power 9 at 4 minutes was the best combination. Complete parts a) and b) below. a) He concluded that this popping method achieved the goal of fewer than 11% of the kernels left unpopped. If it really does not work that well, what kind of error did Josh make? Type Il error Type I error b) To be sure that the method was successful, he popped 8 more bags of popcorn (selected at random) at this setting. All were of high quality, with the percentages of unpopped kernels shown below. 12.4, 2.9, 8.6, 8.1, 13.4, 3.2, 2.7, 9.5 O Does this provide evidence that he met his goal of an average of fewer than 11% unpopped kernels?

A researcher is interested in the effects of diazepam on anxiety in rats. She takes a group of 15 female rats and injects them with 0.005 mg of diazepam for every 100 g the rats weigh, and takes a different group of female rats and injects them with saline. She then puts them all on an elevated-plus maze for 15 minutes and observes how long they spend (in seconds) in the enclosed arms versus the open arms. The less time they spend in the enclosed arms means they have less anxiety. She also weighs them before the injection to make sure she gets the dosage correct. a. Identify the population of interest b. Identify the Independent variable. c. Identify the Dependent variable. d. What scale of measurement was used for the independent variable? Explain why you think so. e. Was the independent variable discrete or continuous? Explain why you think so. f. What scale of measurement was used for the dependent variable? Explain why you think so. g. How could you change the dependent measurement…
