- One study investigated whether the thickness of the banana peel is related to the banana variety and the fertilizer used. The research examined 4 different banana varieties and 3 different fertilizers.The following values were calculated from the data:SSr = 3.4 SSc =1.3 SSe =1.2The research first set out to find out if there is a difference in the average thickness of the banana peel between the fertilizers used. The used fertilizers are presented in the material with columns.Calculate the p-value of the test. Give the answer to two decimal places. Remember the correct decimal separator.Three types of fertilizer were used on 126 identical plots of maize. Each plot was harvested and the yield (in kg) was recorded. Type of Fertilizer Yield (kg) I II III Row Total 0–2.9 11 10 15 36 3.0–5.9 16 21 11 48 6.0–8.9 16 16 10 42 Column Total 43 47 36 126 Use a 5% level of significance to test the hypothesis that type of fertilizer and yield of maize are independent. Interpret the results.What is the level of significance? Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.)What are the degrees of freedom?During a particularly dry growing season in a southern state, farmers noticed that there is a delicate balance between the number of seeds that are planted per square foot and the yield of the crop in pounds per square foot. The yields were the smallest when the number of seeds per square foot was either very small or very large. The data in the table show various numbers of seeds planted per square foot and yields (in pounds per square foot) for a sample of fields. A 2-column table with 15 rows. Column 1 is labeled number of seeds (per square foot) with entries 28, 75, 30, 43, 71, 35, 40, 59, 66, 79, 85, 81, 16, 33, 16. Column 2 is labeled yield (pounds per square foot) with entries 131, 171, 132, 166, 169, 150, 161, 183, 173, 161, 147, 157, 86, 145, 86. Which scatterplot represents the seed and yield data? A graph titled number of Seeds and Crop Yield has seeds (per square foot) on the x-axis, and yard (pounds per square foot) on the y-axis. The points curve up to a point, and…
- The table below shows the parameters for four multiple linear regression bridge deterioration models. The full model has age as continuous independent variable, traffic (Average Daily Traffic (ADT)) and bridge design as categorical variables. The bridge design is expressed as codes “H’ or “HS” for a single-unit truck and a tractor pulling a semitrailer respectively. The numeric suffix represents the gross weight in tons for H truck or weight on the first two axle sets of the HS truck. For example, H_10 denotes a truck with a gross work of 10 tons. The table also contains the following model validation indicators: adjusted r-squared, Akaike’s Information Criteria (AIC), Mean Absolute Error (MAE) and Bayesian Information Criteria (BIC). Write the multiple regression equation for each of the four models and comment on the accuracy of prediction of bridge deterioration of each model.The table below shows the parameters for four multiple linear regression bridge deterioration models.

People familiar with these trees understand that the height of a California redwood tree is related to other characteristics of the tree, including the diameter of the tree at the breast height of a person. The data in the table represent the height (in feet) and diameter (in inches) at the breast height of a person for a sample of 21 California redwood trees. Assuming a linear relationship, use the least- squares method to compute the regression coefficients b0 and b1. State the regression equation that predicts the height of a tree based on the tree’s diameter at breast height of a person. Interpret the meaning of the slope in this equation. Predict the mean height for a tree that has a breast height diameter of 25 inches.

They measured the concentration of ammonium, a molecular form of organic nitrogen, in the soil, and measured or manipulated the density of pickleweed and cordgrass. Manipulations of ½ meter square plots (20 plots per manipulation) included removing all cordgrass (cordgrass removal), removing all pickleweed (pickleweed removal), or mixed (the control - nothing removed, thus mixed plots included a mixture of natural pickleweed and cordgrass). Boxplots of ammonium concentrations in each of the three manipulation treatments. Letters indicate differences among means as determined by a Tukey posthoc test following ANOVA.
