Write down the estimated regression equation. What is the value of R square in this regression model? Compared with the R-square in Question 1, what is the additional contribution of gender to the percentage of variance explained? Interpret the meaning of the regression coefficient of Year in College (how does year in college affect salary?). Does this variable have a significant impact on income level at α= .05? How does one more year in college affect salary if the gender is the same? How do you get this conclusion?
An article in Knee Surgery Sports Traumatology, Arthroscopy, "Effect of provider volume on resource utilization for surgical procedures," (2005, Vol. 13, pp. 273-279) showed a mean time of 113 minutes and a standard deviation of 10 minutes for ACL reconstruction surgery for high-volume hospitals (with more than 300 such surgeries per year). If a high- volume hospital needs to schedule 10 surgeries, what is the mean and variance of the total time to complete these surgeries? Assume the times of the surgeries are independent and normally distributed.
In an experiment, 25 observations were collected and the results are displayed in the histogram below. (a) Describe the shape of this histogram. (b) Which quantity do you expect to be larger, the mean or the median? Explain. (c)Which statistic best describes the center of these data? [Here, you are giving the name or symbol of the statistic. You do not need to calculate or estimate its value.] (d)Which statistic best describes the spread of these data? [Here, you are giving the name or symbol of the statistic. You do not need to calculate or estimate its value.]
The results above were obtained because the sample means are close together. To construct the data set below, the same scores from above were used, then the size of the mean differences were increased. In particular, the first treatment scores were lowered by 2 points, and the third treatment scores were raised by 2 points. As a result, the three sample means are now much more spread out. Before you begin the calculation, predict how the changes in the data should influence the outcome of the analysis. That is, how will the F-ratio for these data compare with the F-ratio from above? TTT Treatment A Treatment B Treatment C 10 13 17 14 15 16 10 17 20 14 15 19 F-ratio = p-value Conclusion: O There is a significant difference between treatments O These data do not provide evidence of a difference between the treatments Submit Question Ce

Environment statistics are statistics that describe the state and trends of the environment, covering the media of the natural environment (air/climate, water, land/soil), the biota within the media, and human settlements. The chi-squared test has been one of the most frequently used in environmental studies. you are required to explain in detail what is chi-square test, the usage on type of data, assumptions associated with its application, identify a dataset related to the environmental study and conduct the relevant chi- squared test. You are required to show the calculations manually as well as to make use of the online calculator or software to calculate the chi-square statistics and its associated p-value. b.
Advertising aimed at teenagers tends to contain dance-beat music, adventure, and a fast pace rather than words. To test to see how teenagers respond to different types of commercials, 150 teenagers then watched a set of commercials with dance-beat music, adventure, and a fast pace. After the commercials, the teenagers were asked whether they would want to buy the product and 102 responded that they would buy the product. Another sample of 125 teenagers where shown a set of commercialscomprised primarily of words. After the commercials, the teenagers were asked whether they would buy the product and 60 responded that they would like to buy the product. Based on both samples, at the 5% level of significance, test the hypothesis that there is at least a 10% difference in the proportion of teenagers who would buy the product after watching the different types of commercials?
