Research was conducted to find out the relationships between pro-environmental attitudesand 20 concepts of nature. As expected, the pro-environmental attitudes were related toseveral of the concepts of nature measured. One of the possible research objectives in thisstudy is to assess the relationship between level of knowledge on nature or theenvironment (X), and the frequency of engaging in pro-environmental behavior (Y) permonth, e.g., recycling and using biodegradable products. The data from your study (from 15respondents) are as follows:IDYXYy21712371158199748.119.21081611712191371014713153ТОTAL Calculate the slopeAnswer:Provide the equation of the straight line between X and YAnswer:

Forest bathing, also called Shinrin-yoke, is the practice of taking short, leisurely walks in a forest to enhance positive health. To test if forest bathing and mood are related, a clinical psychologist records the time spent forest bathing in minutes (X) and the corresponding change I mood using a standard self report affect grid (Y) among 8 patients with a history of depression. The data are given in the following table. times spent forest bathing (in minutes) change in mood X Y 32 +24 24 +20 28 +25 17 +22 12 +16 Compute the method of least squares to find the equation of the regression line. Use the regression equation computed in part (a) to determine the predicted change in mood of a person who spends 20 minutes forest bathing.
Suppose that as part of a research methods class, Bailey was asked to write summaries of research papers on the following topics. • The effects of increasing temperatures on the migration patterns of birds • The effects of media coverage on community support for crime prevention For each topic, identify the explanatory and the response variables. Temperature and the level of community support for crime prevention are the explanatory variables, and the amount of media coverage and the migration patterns of birds are the response variables. Temperature and the amount of media coverage are the response variables, and the migration patterns of birds and the level of community support for crime prevention are the explanatory variables. Temperature and the amount of media coverage are the explanatory variables, and the migration patterns of birds and the level of community support for crime prevention are the response variables.

well-known multinational FMCG produces more than fifty products and sells them in the market. Out of fifty products one is mineral water for drinking purpose and supplies different size pack bottles in the market. Product manager observed that, during hot days the sale of water is more as compared to the normal days. He started the collection of data of weekly sale of water and the average weekly temperature. Product manager was interested in developing a relationship between sales and temperature; therefore, he discussed and shared the following data with you. sales 75 77 69 63 79 80 77 70 73 87 72 73 80 80 69 84 77 72 74 81 temperature 32 36 31 31 34 29 32 35 28 31 30 31 29 35 36 28 32 33 32 33 Sale is in thousand liters and temperature is in degree Celsius.

A significant interaction was found between depression, social support and GPA. These results should be considered with caution and further research should be done to better understand the relationships between these variables. Furthermore, those working with college students should consider the overall well-being of the student, as it is possible that their academic performance may not be affected by anxiety and/or depression. IS THIS A TYPE 1 ERROR OR A TYPE 2 ERROR IN RESEARCH?
Suppose researchers at an abdominal transplant clinic are concerned about the rate of graft loss due to diabetes status prior to receiving a donor kidney. Research has shown that gender discordance, or receiving a gender from a donor of an opposite gender may increase the risk of both exposure and outcome after transplant. Assume the following tables represent the stratified analysis of the potential confounding variable. (9 points) Gender Discordance Graft Failure No Graft Failure Total Diabetes II 23 10 33 No Diabetes II 4 44 48 Total 27 54 81 Gender Concordance Graft Failure No Graft Failure Total Diabetes II 9 34 43 No Diabetes II 12 87 99 Total 21 121 142 A) Calculate the stratum specific estimates for the odds ratios in each strata. B) Observe the difference in the odds ratios. Based on observation alone, what are we likely to conclude regarding the relationship between outcome and exposure…
