Ceramics engineers are testing a new formulation for the materials used to make insulators for power lines. They will try baking the insulators at three different temperatures (low, medium, or high) followed by cooling at two different speeds (slow or rapid). They are interested in testing all combinations of baking temperature and cooling speed to see which combinations produce insulators least likely to break during adverse weather conditions. How many combination of factors and levels, called treatments, are being proposed in the experimental design? O a. 8 O b.6 Oc. 2 O d.4

2. Floods: Rapid drainage of floodwater is crucial to prevent damage during heavy rains. Several designs for a drainage canal were considered for a certain city. Each design was tested five times, to determine how long it took to drain the water in a reservoir. The following table presents the drainage times, in minutes. Channel Type Drainage Time 1 41.4 43.4 50.0 41.2 2 38.7 48.3 51.1 38.3 3 32.6 33.7 34.8 22.5 4 26.3 30.9 33.3 23.8 5 44.9 47.2 48.5 37.1 a. Construct an ANOVA table. b. Can you conclude that there is a difference in the mean drainage times for the different channel designs? Use the α = 0.01 level of significance.
The output of a solar panel (photovoltaic) system depends on its size. A manufacturer states that the average daily production of its 1.5 kW system is 6.6 kilowatt hours (kWh) for Perth conditions. A consumer group monitored this 1.5 kW system in 20 different Perth homes and measured the average daily production by the systems in these homes over a one month period during October. The data is provided here. kWh 6.2, 5.8, 5.9, 6.1, 6.4, 6.3, 6.9, 5.5, 7.4, 6.7, 6.3, 6.2, 7.1, 6.8, 5.9, 5.4, 7.2, 6.7, 5.8, 6.9 1. Analyse the consumer group’s data to test if the manufacturer’s claim of an average of 6.6 kWh per day is reasonable. State appropriate hypotheses, assumptions and decision rule at α = 0.10. What conclusions would you report to the consumer group? (Hint: You will need to find Descriptive Statistics first.) 2. If 48 homes in the central Australian city of Alice Springs had this system installed and similar data was collected, in order to assess whether average daily production in…
T1. Colors in print media, on computer monitors, and on televi- sion screens are implemented using what are called "color mod- els". For example, in the RGB model, colors are created by mixing percentages of red (R), green (G), and blue (B), and in the YIQ model (used in TV broadcasting), colors are created by mixing percentages of luminescence (Y) with percentages of a chromi- nance factor (I) and a chrominance factor (Q). The conversion from the RGB model to the YIQ model is accomplished by the matrix equation .299 .587 .114 I .596 -.275 -.321 G .212 -.523 .311 B What matrix would you use to convert the YIQ model to the RGB model?

Data from the US Department of Energy’s US Energy Information Administration (eia.doe.gov) provides a look at the energy-related carbon dioxide emissions by end use sector (residential, commercial, industrial, transportation) from years 1990 to 2009. (Report # DOE/EIA0573(2009)). Here we would like to see if the CO2 emissions from the Industrial sector are less than that from the Transportation sector. Below are the results: 14. What type of study is this? a. Paired b. Two-Sample Independent 15. What type of plot would we use? a. Histogram of the differences b. Side-by-side boxplots c. Pie chart d. Bar graph 16. Was the HOV/pooled test used above (hint: look at the df)? YES NO 17. Is there evidence that the CO2 emissions from the Industrial sector are less than that from the Transportation sector? YES NO 18. If we were to test to see if there was a difference between the CO2 emissions from the Industrial sector and the Transportation sector, what would be the p-value? (report to 3…
Yvon Hopps ran an experiment to determine optimum power and time settings for microwave popcorn. His goal was to find a combination of power and time that would deliver high-quality popcorn with less than 10% of the kernels left unpopped, on average. After experimenting with several bags, he determined that power 9 at 4 minutes was the best combination. To be sure that the method was successful, he popped 8 more bags of popcorn (selected at random) at this setting. The data below report the percentages of uncooked popcorn. 2.9 2.8 5.2 6.7 7.0 7.8 10.8 13.2 (a) Using a computer or calculator, calculate the sample mean and the sample standard deviation s. Clearly indicate which quantity is which using the correct symbols and round your answers to two decimal places, if necessary. (b) What percent of unpopped kernels is 3 standard deviations above the mean?
An article in the San Jose Mercury News stated that students in the California state university system take 4.5 years, on average, to finish their undergraduate degrees. Dr. Lewis believes the mean time for students at Clayton State University is longer than this average. A survey of 49 graduates from Clayton State had a mean time of 5.1 years to complete their Bachelor's degree, with a sample standard deviation of 1.2 years. Correctly identify the null and alternative hypotheses for this study:
Air pollutants common in U.S. cities include fine particulate matter (PM) and ozone (O3). PM is measured as “inhalable” particles 10 micrometers in diameter or “fine inhalable” particles 2.5 micrometers in diameter. Suppose that studies show, for a particular region, that cities exceed PM2.5 standards 20% of the time and exceed ozone standards 10% of the time. Assume that PM2.5 and ozone measurements are statistically independent. A) Determine the probability that a city, selected at random, exceeds one of the standards. B) If a city exceeds the standards, what is the probability that it exceeds only the PM2.5 standard?
The manager of the city pool has scheduled extra lifeguards to be on staff for Saturdays. However, he suspects that Fridays may be more popular than the other weekdays as well. If so, he will hire extra lifeguards for Fridays, too. In order to test his theory that the daily number of swimmers varies on weekdays, he records the number of swimmers each day for the first week of summer. Test the manager’s theory at the 0.0250.025 level of significance.

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 202343207163119 19227203324343 92434142020829 18–19 4020371636483818 3118102312151422 2547383338253033 20–21 2617152026382223 2029292641192731 2830194245413845 Using MS Excel, conduct a 2-way ANOVA with α=0.05α=0.05.

Terrariums are self-contained ecosystems inside a closed container. A local farmer produces terrariums for sale, but must wait for the plants in the terrarium to grow before she can sell them. On average, her terrariums take 30 days before they are ready to sell. She experiments with a new soil mixture, aiming to decrease the time it takes for the terrariums to be ready. In a sample of 12 terrariums with the new soil mixture, the farmer finds that the average time before they are ready is 21 days with a standard deviation of 3 days. in testing the hypotheses H0:μ= 30 and Ha:μ< 30, what is the value of the tt-test statistic? Round your answer to three decimal places.
An article on the PureEnergySystems.com website written by Louis LaPoint discusses a product called acetone. The article stated that “Acetone 1CH3COCH32 is a product that can be purchased inexpensively in most locations around the world, such as in common hardware, auto parts, or drug stores. Added to the fuel tank in tiny amounts, acetone aids in the vaporization of the gasoline or diesel, increasing fuel efficiency, engine longevity, and performance—as well as reducing hydrocarbon emissions.” To test whether this product actually does increase fuel efficiency in passenger cars, a consumer group has randomly selected 5 people to participate in the study. The following procedure is used: People are to bring their cars into a specified gasoline station and have the car filled with regular, unleaded gasoline at a particular pump. Nothing extra is added to the gasoline at this fill-up. The car’s odometer is recorded at the time of fill-up. When the tank is nearly empty, the person is…
