## Investigation of Fuel Additives on Vehicle EfficiencyTwo fuel additives are assessed to determine their effects on miles per gallon (mpg) for passenger cars. Results for 12 cars are provided, each tested with both additives.| Car | Additive 1 | Additive 2 ||-----|------------|------------|| 1 | 20.12 | 18.05 || 2 | 23.56 | 20.77 || 3 | 21.03 | 21.57 || 4 | 19.15 | 16.06 || 5 | 21.23 | 20.22 || 6 | 24.77 | 23.8 || 7 | 16.16 | 16.16 || 8 | 18.55 | 13.98 || 9 | 20.87 | 20.03 || 10 | 23.23 | 21.15 || 11 | 23.21 | 21.78 || 12 | 24.02 | 22.7 |### Statistical TestingUtilizing a significance level of α = 0.05, the Wilcoxon signed-rank test is employed to evaluate whether there is a significant difference between the median mpg for the additives.#### a. Hypotheses- **Null Hypothesis (H₀):** Median for Additive 1 minus Median for Additive 2 equals 0- **Alternative Hypothesis (H₁):** Median for Additive 1 minus Median for Additive 2 does not equal 0Both hypotheses are correctly stated with checkmarks next to them.#### b. Mean and Standard Deviation- **Mean:** 39 ✓- **Standard Deviation:** 25.4951 ✗ (incorrect)These values pertain to the distribution used in the statistical analysis.

A certain county had a population of 34,485 people. The county hospital is interested in estimating the number of people in the county with blood type-O. To do this, they test blood samples from 228 patients. Out of this group, 10 have blood type-O. Use this sample to estimate the number of people in the county with blood type-O.
A study was carried out to determine the influence of a trace elementfound in soil on the yield of potato plants grown in that soil, defined asthe weight of potatoes produced at the end of the season. A large fieldwas divided up into 14 smaller sections for this experiment. For eachsection, the experimenter recorded the amount of the trace elementfound (in milligrams per metre squared) and the corresponding weightof the potatoes produced (in kilograms). This information is presentedin the worksheet ‘Dataset5’ in the Excel document. Define X as thetrace element amount and Y as the yield.1. Draw a scatterplot of your data set.Page 52. Calculate the coefficients of a linear equation to predict the yieldY as a function of X.3. Calculate the correlation coefficient for the paired data values.4. Set up the framework for an appropriate statistical test to establish if there is a correlation between the amount of the trace element and the yield. Explain how having the scatterplot referredto…
A researcher hypothesized that cytokinins and auxins supplied by tumor-inducing insects lead to the production of tumors in plants. She performed experiments in which she hypodermically injected green pepper plants to determine if she could induce tumors. In one experiment she varied the concentration of cytokinin and the ratio of auxin concentration to cytokinin concentration. She used 3 concentrations of cytokinin and 6 ratios of auxin/cytokinin. The concentrations are indexed (1-3) with 3 indicating the highest concentration of cytokinin. The 6 ratios of auxin/cytokinin varied from 0.125 to 5.0 with values greater than 1 indicating that auxin was in greater concentration than cytokinin. The resulting data are in the date file "auxcyt.csv". The measured sizes of the tumors induced (relative to controls) are given in the 3rd column ('sumdiffd'). Analyze these data testing the appropriate hypotheses and interpret the results. (Note the unequal sample sizes.) auxcyt data…

The valence of a song is measured from 0 to 10 and detects the musical positiveness conveyed in the song. Tracks with high valence sound more positive (e.g. happy, ch with low valence sound more negative (e.g. sad, depressed, angry). The valence was computed for 42,000 songs on Spotify in the genres of Techno, Techhouse, Trance, Trap, Psytrance, DnB, Hardstyle, Underground Rap, Trap Metal, Emo The table below shows the number of songs with a given valence measurement.

A college administrator wants to know if there is a significant difference between sexual orientation and level of family support for students at their college. The administrator takes a random sample of students who identify as gay/lesbian, bisexual or heterosexual/straight. There were 22 students sampled in each category. A measure of family support is given with higher scores indicating more family support. The means are as follows: Gay/lesbian Bisexual Heterosexual/Straight MG/L = 16 MBi = 17 MH/S = 22 Source SS df MS F Orientation 300 Error 2961 Total What is the value of df total?

Some commercial airplanes recirculate approximately 50% of the cabin air in order to increase fuel efficiency. The researchers studied 1100 airline passengers, among which some traveled on airplanes that recirculated air and others traveled on planes that did not recirculate air. Of the 515 passengers who flew on planes that did not recirculate air, 108 reported post-flight respiratory symptoms, while 112 of the 585 passengers on planes that did recirculate air reported such symptoms. Is there sufficient evidence to conclude that the proportion of passengers with post-flight respiratory symptoms differs for planes that do and do not recirculate air? Test the appropriate hypotheses using ? = 0.05. You may assume that it is reasonable to regard these two samples as being independently selected and as representative of the two populations of interest. (Use a statistical computer package to calculate the P-value. Use pdo not recirculate − pdo recirculate. Round your test statistic to two…
