A researcher conducts a research study to examine whether there is a difference between two treatments regarding depression. Which of the following is consistent conceptually with the alternative hypothesis?

For the following hypotheses, identify the independent and dependent variables. States with more restrictions on obtaining abortions will have lower abortion rates. Counties paying teachers more will have higher standardized test scores. The lower a state’s per capita income, the less money spent per resident on road maintenance.

Only the question 5 and 6 need to be resolved. Others have been reaolved already. Question: sample of 15, 10 years old children was taken to study whether watching television reduces the amount of physical exercise, causing weight gains. The number of kilograms each child was overweight by was recorded (a negative number indicates the child is underweight). In addition, the number of hours of television viewing per week was also recorded. These data are listed in the table below. Television(hours)             42   34   25   35   37   38   31   33   19    29   38   28   29   36   18 Overweight (Kg)                 8      3     0      0    6      6     3     3     -4     4     4      2     1     6     -3 Use an appropriate plot to investigate the relationship between Television(hours) and Overweight (KG). Briefly explain the selection of each variable on the X and Y axes and why?  Calculate and interpret the coefficient of correlation (r) between Television(hours) and Overweight (KG).…

For a within-subjects study comparing two treatments, A and B, a researcher expects that practice in the first treatment will improve the participants scores in the second treatment. If the order of treatments is counterbalanced, then the practice will… A. Influence scores in treatment A, but not in treatment B B. Influence scores in treatment A for half the participants and scores in treatment B for half the participants C. Not influence the scores in either treatment condition because the treatments are counterbalanced D. Influence scores in treatment B, but not in treatment A

In a study carried out among low-income families in the young towns of Detroit, it was found that 30% spent less than $8 weekly on purchasing charcoal and consumed products from soup kitchens. 35% spent $8 to $15 weekly on the purchase of charcoal. 5% spent more than $15 weekly on the purchase of charcoal and consumed products from the soup kitchen. 15% spent more than $15 each week buying coal. Finally, 55% did not consume the products of the soup kitchens.If you randomly choose a low-income familyto. What is the probability that you spend less than $8 weekly on purchasing coal?b. What is the probability that you do not consume the products of the soup kitchens and spend 8 to 15 dollars buying charcoal?C. If the family spends more than $15 weekly on purchasing charcoal, what is the probability that they will not consume the products from the soup kitchens?d. If the family does not consume products from soup kitchens, what is the probability that it will spend less than 8 soles per…

The hypothesis should revolve around one of the variables collected for all subjects. Your results section should describe the general course of one subject’s response from your individual analysis and then evaluate your hypothesis for a specific collective variable.    Please explain this in plain english. I dont understand the instructions. Here is a reference of the subjects.

Give an example of an experiment for each of the following. (1. single-blind experiment with the subjects blinded a. An experiment where researchers use two groups and give one group a placebo treatment and the other group the treatment of interest and then measure the results. b. An experiment where researchers use two groups and give one group a placebo treatment and the other group the treatment of interest, but don't tell the groups which is which, then measure the results.    c. An experiment where researchers use two groups and give one group the treatment of interest and the other group no treatment, then measure the results. dAn experiment where researchers use two groups and give one group a placebo treatment and the other group the treatment of interest, but do not tell the people taking measurements or the groups which group is which, then measure the results. e. An experiment where researchers use two groups and give one group the treatment of interest and the other…

Researchers are interested in whether the presence of another person influences one’s level of self-reported stress when performing a public speaking tasks. Participants performed the public speaking task on three different occasions. Once in the presence of a friend who provided support, another time in the presence of a stranger who provided support, and a third time alone, without any support
