Question

Ability to grow in shade may help pines found
in the dry forests of Arizona to resist drought.
How well do these pines grow in shade?
Investigators planted pine seedlings in a
greenhouse in either full light, light reduced to
25% of normal by shade cloth, or light reduced
to 5% of normal. At the end of the study, they
dried the young trees and weighed them.
What are the explanatory variables, treatments,
and response variables for this experiment?

Researchers have noted a decline in cognitive functioning as people age (Bartus, 1990). However, the results from other research suggest that the antioxidants in foods such as blueberries may reduce and even reverse these age-related declines (Joseph et al., 1999). To examine this phenomenon, suppose that a researcher obtains a sample of n = 16 adults who are between the ages of 65 and 75. The researcher uses a standardized test to measure cognitive performance for each individual. The participants then begin a 2-month program in which they receive daily doses of a blueberry supplement. At the end of the 2-month period, the researcher again measures cognitive performance for each participant. The results show an average increase in performance of MD = 7.4 with SS = 1215. Does this result support the conclusion that the antioxidant supplement has a significant effect on cognitive performance? Use a two-tailed test with α = .05. Show your computations.
Researchers studied 208 infants whose brains were temporarily deprived of oxygen due to complications at birth. When researchers detected oxygen deprivation, they randomly assigned babies to either usual care or to a whole-body cooling group. The goal was to see whether reducing body temperature for three days after birth increased the rate of survival without brain damage. What is the explanatory variable? A. Survival without brain damage B.Infants whose brains are temporarily deprived of oxygen C. Usual care or whole-body cooling
In random samples of 900 men and 400 women it is found that 99 men and 36 women suffer from kidney stones. Is there statistical evidence that the proportion of male kidney stone sufferers is greater than the proportion of female kidney stone sufferers? Use 5% significant level.
The drug Tamiflu (oseltamivir phosphate) is used to attack the influenza virus to reduce symptoms for patients. The manufacturer label states that 7% of patients will develop nausea as a side effect. Patients report that nausea occurs at a higher rate than the label indicates. In clinical trials, among 670 patients treated with Tamiflu, 82 experienced nausea as a side effect. Using an α=0.05 level of significance, complete the following steps to determine whether the rate of developing nausea is higher than the manufacturer’s label. (NOTE: All areas are reported to four decimal places; all z-scores are reported to two decimal places except the two special cases listed at the bottom of the table.) Insert the following values from the question: p = Answer% = Answer (two decimals) q = Answer (two decimals) x = Answer n = Answer p̂ = Answer (four decimals) α = Answer Set up the hypothesis statements (no spaces between characters): H0: Answer H1: Answer Based on the hypothesis…
The human resource manager of company wanted to know how the Performance of the workers depend on Environment, Value, Motivation and Remuneration. He selected 100 workers randomly and used a questionnaire to obtain the scores on their perceived Environment, Value, Motivation and Remuneration. The final score on each variable ranged from 1 to 10, where a high score is supposed to be associated with high performance. In the study, the key performance index (KPI) was used as the indicator of worker performance. The following are some of the outputs from SPSS. What are the significant predictor(s) of Performance? Predict the Performance for a customer with the following scores: Environment =7, Value=4, Motivation=5 and Remuneration=6.
