KYou want to compare the tastiness and tanginess of limes grownwith three amounts of a new fertilizer (none, half therecommended amount, and the full recommended amount). Youallocate 22 lime trees to receive each amount of fertilizer,assigning them at random. What are the experimental units?What is the response variable?What were the experimental units?O A. The experimental units are amounts of fertilizer used oneach tree.B.The experimental units are the lime trees.OC.The experimental units are the different amounts offertilizer (none, half the recommended amount, and thefull recommended amount).D. The experimental units are the measured tastiness andtanginess of each lime.What is the response variable?OA. The response variable is the different amounts offertilizer (none, half the recommended amount, and thefull recommended amount).B. The response variable is the overall outcome of theexperiment.OC. The response variable is the tastiness and tanginess ofthe limes.OD. The response variable is the amount of fertilizer usedon each tree.

Experiment is that whether tastiness and tanginess of limes grown differ with three amounts of…

You are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats.You sample 190 men, and 40% own cats.You sample 90 women, and 50% own cats.Find the proportion of the pooled samples, (pc), as a decimal, rounded to two decimal places.
A researcher was interested in how much longer the heart rate recovery time is for untrained college students compared to athletically trained college students. Eleven athletically untrained college students and nine athletically trained college students were put on a treadmill for fifteen minutes and then tested to see how many minutes it took for their heart rates to return to normal. The results of the study are shown below. Untrained: 8, 7, 7.2, 6.9, 7.8, 8.8, 8, 8, 8.8, 7.3, 8.6 Trained: 1.5, 1.5, 1.8, 2, 1.9, 2.3, 2.3, 2.4, 2.2 Assume both follow a Normal distribution. Compute the 95% confidence interval for the difference. Round to one decimal place. ( ___________ , _____________ )
Problem: An administer claims that the proportion of students who pass a particular test given to all college freshmen is 77.32%. To test the claim an SRS of size 199 test scores was collected. The sample had 74 students pass the test. Find the test statistic.
A randomly sampled group of patients at a major U.S. regional hospital became part of a nutrition study on dietary habits. Part of the study consisted of a 50-question survey asking about types of foods consumed. Each question was scored on a scale from one (most unhealthy behavior) to five (most healthy behavior). The answers were summed and averaged. The population of interest is the patients at the regional hospital. The current survey was implemented after patients were subjected to this education, and it produced the following sample statistics for 25 patients sampled: and s = 1.02. We would like to know if the education improved nutrition behavior. We test the hypotheses H 0: = 2.9 versus Ha: > 2.9. The value of the t test is 1.96, and: a. P-value > 0.1. b. 0.025 P-value < 0.05. c. 0.25 P-value < 0.01. d. 0.05 P-value < 0.1. Given the least squares regression line y = 3 x – 3, which of the following is true? a. The…

A substance abuse counselor wants to demonstrate the effect of situational stress on alcohol cravings. He recruits two groups of men who are similar in respect to history of alcohol use and demographic variables. He divides them in to two groups. In one group(n=11), the men are exposed to a stressful situation and then asked to complete a measure rating their alcohol cravings on a scale from 0-10, where 0 representsno cravings and 10 represents intense cravings. In the second group (n=10), the men are exposed to a neutral situation and asked to complete the same measure. What test and graph should I create to find out if a stressful situation result in more intense alcohol cravings than a non-stressful situation?
r. Lyte wishes to study speed of Reaction Time to press a button in response to the onset of a lamp. The independent variable (IV) is the color of the light produced by the lamp (red, orange, yellow, green, or blue). Since only 10 participants are available, she elects to administer the IV within-subjects with all 10 participants being exposed to all five levels of the color variable. The order of the color of the light presentation is to be counterbalanced. Using concepts from the textbook, why would Dr. Lyte need to use counterbalancing in this scenario?
I am having trouble solving this problem. Can you please provide me with some help? Thank you. I appreciate it. Almonte. Inc., a maker of low-priced hair care products, claims that its hair spray lasts as long as the industry leader's higher-priced product. You take a sample of 60 applications of Almonte's hair spray and 60 applications of the leading hair spray. Results: On average, the Almonte applications held for 12.7 hours with a standard deviation of 1.4 hours. On average, the leading hair spray lasted 11.8 hours with a standard deviation of 1.8 hours. Set up a hypothesis test to test whether the difference in sample means is statistically significant. Use a significance level of 1%. Report and explain your conclusion.
You are testing the claim that the proportion of men who own cats is significantly different than the proportion of women who own cats. You sample 150 men, and 15% own cats. You sample 110 women, and 20% own cats. Find the pooled value of p, as a decimal, rounded to two decimal places.
Four factors are thought to influence the taste of the dietary product: A - type of sweetener; B – fruit content; C – percentage fat matter; D - temperature. A full factorial experiment was conducted with these 4 factors. At each run in the design, samples of the dietary product were tested by panel of experts who rated the taste on a scale from 1 to 10, the response variable taken being the sum of individual ratings. The results are listed in the table below, in the standard order of runs. Generate the design for this experiment, analyse the results by producing main effects and interactions plots and discuss the most significant factors that can be used to find a formulation that maximises the total score. Run (std order) 1 2 4 7 8 10 11 12 13 14 15 16 Total score 169 178 168 176 185 189 183 189 174 197 173 195 178 207 180 204
Determine whether the study depicts an observational study or an experiment. A scientist was studying the effects of a new fertilizer on crop yield. She randomly assigned half of the plots on a farm to group one and the remaining plots to group two. On the plots in group one, the new fertilizer was used for a year. On the plots in group two, the old fertilizer was used. At the end of the year the average crop yield for the plots in group one was compared with the average crop yield for the plots in group two.
Phosphorous is a chemical that is found in many household cleaning products. Unfortunately, phosphorous also finds its way into surface water, where it can harm fish, plants, and other wildlife. Two methods of phosphorous reduction are being studied. At a random sample of 7 locations, both methods were used and the total phosphorous reduction (mg/L) was recorded. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value a small amount and thereby produce a slightly more "conservative" answer. Things that are labelled i underneath a b c, etc are all part of that part.
