An experiment was conducted to observe the effect of an increase in temperature on the potency of an antibiotic. Three 1-ounce portions of the antibiotic were stored for equal lengths of time at each of the following Fahrenheit temperatures: 40, 55, 70, and 90. The potency readings observed at the end of the experimental period were Potency reading, y: 49 38 27 24 38 33 19 28 16 18 23 Temperature, x: 40 40 40 55 55 55 70 70...

1. An experiment is to be conducted to assess effect of temperature on the amount of impurities removed by using water samples contaminated with the same level of impurity. Six samples are to be tested at each of 5 temperatures and the amount of impurities removed in each sample recorded. (a) What is the response variable? (b) What is the factor of interest? (c) What are the levels of this factor? (d) What experimental design is suitable? (e) Describe how...

Design an experiment that tests the effect of body temperature on the aerobic capacity in an animal of your choice. What variables would you measure, and how? Include detail about experimental design and instrumentation, to show your understanding of how data are acquired. Present hypothetical data (in graphical form), which support your predictions. Make sure to label your graphs accurately and precisely, and use reasonable values (and units) for parameters measured.

Emissions of nitrogen oxides, which are major constituents of smog, can be modeled using a normal distribution with a mean of 1.7 ppb and a standard deviation of 0.4 ppb. Suppose 14 cars are selected at random. What is the probability that the average emissions of the 14 cars is less than 1.5 ppb? Picture: Z-score: Answer:

An experiment was conducted to investigate the effect of extrusion pressure (P) and temperature at extrusion (T) on the strength y of a new type of plastic. Two plastic specimens were prepared for each of five combinations of pressure and temperature. The specimens were then tested in a random order and the breaking strength for each specimen was recorded. The independent variables were coded (transformed) as follows to simplify the calculations: x1= (P-200)/10, x2= (T-400)/25. The n=10 data points are...

In an experiment to determine the effect of nutrition on the attention spans of elementary school students, a group of 45 students is divided into three groups of 15, and randomly assigned to each of three meal plans: no breakfast, light breakfast, and full breakfast. Their attention spans, in minutes, were recorded. Say you want to test the hypothesis that the means of the attention spans are not all the same at a level of significance of 5%. (a) (3...

An experiment was performed to determine the effect of four different chemicals on the strength of a fabric. These chemicals are used as part of the permanent press finishing process. Five fabric samples were selected, and a randomized complete block design was run by testing each chemical type once in random order on each fabric sample. The data are shown in Table below. test for differences in means using an ANOVA with α=0.01 Fabric Sample Chemical Type 1 2 3...
