Problem #1: Cotton Tensile StrengthThe Sturdy Fabric recently started an investigation into the formulation of synthetic fibers thatare used to make cloth. The response the company is interested in is the tensile strength of thefiber. The experimenter wants to determine the best level of the cotton in terms of percent, toachieve the highest tensile strength of the fiber. Therefore, we have a single quantitative factor,the percent of cotton combined with synthetic fabric fibers.The five treatment levels of percent cotton are evenly spaced from 15% to 35%. We have fivereplicates, five runs on each of the five cotton weight percentages.ObservationsCotton1 2 3 4 57 7Weight Percentage1515 11 92012 17 12 18 182514 18 18 19 193019 25 22 19 2335710 11 15 111)-Use Minitab or other software to conduct Analysis of Variance and determine the best level(Percentage) of cotton that results in highest fiber strength2)- Interpret the output (Analysis of Variance Table)

Radon is a gas emitted from the ground that can collect in houses in buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable” Radon levels in a house vary from week to week. In one house, a sample of 6 weeks had the following readings for radon level (in pCi/L): 1.9 2.8 3.9 3.9 4.2 5.7 Find the variance and standard deviation (definitional formula).

The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for feeding. However, the large surface area may also be an important mechanism for radiating heat (and hence cooling the bird) as outdoor temperature increases. The table contains data for beak heat loss, as a percentage of total body heat loss from all sources, at various temperatures in degrees Celsius. The data show that beak heat loss is higher at higher temperatures and that the relationship is roughly linear.

Joan's Nursery specializes in custom-designed landscaping for residential areas. The estimated labor cost associated with a particular landscaping proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost estimating purposes, managers use two hours of labor time for the planting of a medium- sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours).

Benign prostatic hyperplasia is a non-cancerous enlargement of the prostate gland that adversely affects the quality of life of millions of men. A study of a minimally invasive procedure for the treatment of this condition looked at pretreatment Quality of Life (QOL Base) and Quality of Life (QOL 3Mo) after 3 months on treatment. Quality of Life was rated using an ordinal scale of 0 to 6, where 0 is "Delighted" and 6 is "Terrible" Create a "Delta" column depicting the Difference between the Base and 3-month ratings Find the Mean of the Differences, Standard Deviation and Standard Error for the Delta values Is there a Significant Difference in Quality of Life 3 months after treatment?
