- Our goal is to see whether the global temperatures has been getting higher. For the phrase above, assume the data has already been presented and state a hypothesis. Describe the process one should take to test the hypothesis in detail. How should someone plan to test a hypothesis? Under what circumstances can somebody conclude that the global temperatures has been getting higher?arrow_forwardYour daughter is wasting my husband's money by trying to collect 6 rare photocards from a foreign album. Calculate the average number of albums she needs to buy in order to get all the 6 collectibles. Use the three trials shown below for your simulation.(Note: Treat the data vertically, and in order).arrow_forwardYou conducted a regression analysis between the number of absences and number of tasks missed by your 5 classmates in Statistics and Probability. It resulted that the regression line is y = 0.65x + 1.18. What is the predicted number of tasks missed of a learner who is always present? O a. The learner has 1 task missed. O b. The learner has less than 2 tasks missed. O c. The learner has more than 2 tasks missed. o d. The learner has no task missed.arrow_forward
- For a multiple regression analysis with 2 and 12 degrees of freedom, MS regression is 135 and MS residual is 15. What is the decision for this test?arrow_forwardCalculate the estimated R2 and state why we should consider using adjusted R2 instead of R2 in the setting of multiple linear regression?arrow_forwardAnalyze your data from Exercise 2 (coin toss using 2 coins). Copy your results from there and write under the Observed column. Is my answer correct?arrow_forward
- Please also explain why you determined whether or not the results are statistically significant. A student finds a correlation of r = .04 between the number of units the students in his research methods class are taking and the students’ level of stress.arrow_forwardThe owener of a winery collects data on competing wineries every year. He would like to predict the gross sales (in number of cases) from the size of the wineries (in acres). What is the explanatory variable in this study?arrow_forwardAnother researcher decided to test a similar question in a different way: she collected a sample of dogs whose families lived in the city, and were just about to move to the suburbs. She measured how long each dog was active on a random day before the move (while they were still living in the city) and after the move (when they were in the suburb). What type of test should she use to analyze her data? Explain your answerarrow_forward
- You run a regression analysis on a bivariate set of data (n=24). You obtain the regression equation with a correlation coefficient of r=0.945 (which is significant at a=0.01). You want to predict what value (on average) for the explanatory variable will give you a value of 60 on the response variable. What is the predicted explanatory value ?arrow_forwardA teacher gives a reading skills test to a third-grade class of n = 25 at the beginning of the school year. To evaluate the changes that occur during the year, students are tested again at the end of the year. Their test scores showed an average improvement of MD = 12.7 points with s2 = 100. Which variables are described in this scenario and what are their scales of measurement? Which test should you use?arrow_forwardUse Excel to find an estimated linear regression equation using X1 and X2 as the independent variables and Y as the dependent. Put your output on a fresh sheet. Then answer the following questions (excel chart in the picture) Write down the estimates regression equation What is the expected value of Y if X1 is 240 and X2 is 290? Show your calculation at a 5%level of significance, are the true coefficients of X1 and X2 different from zero? Justify briefly using numbers from your excel output. 4. Using Excel, determine a 97% confidence interval for the true coefficient of X1arrow_forward
