The mean golfing score for all past students who learned with Mr. Palmer is 79. This golfing cycle, he tried a new teaching method using simulations instead of real-world golf. He then had 15 of his students that used his new method take a golfing test. Enter the data into SPSS. Use this dataset to answer this question: did Mr. Palmer’s students perform better on the golfing test using the new method as compared to the traditional teaching technique? 1. From the output, report the test statistic and the probability (obtained p-value, called “sig” in the output). Remember to include degrees of freedom when you report t-values. 2. Will you reject or fail to reject the null based on the SPSS output (Remember to use numbers from the output only to make your statistical conclusion. If you use a critical t, you will get no points.).arrow_forward

Transcription factors are genes that code for proteins that regulate the transcription of multiple other genes. Studies show how transcription factor Zscan1O controls aspects of development in the mice. There was two lines of mice examined, both genetically identical except that one (mutant) carries a mutation in Zscan1O transcription factor The normal line was the control line. They measured the length of one tibia per mouse in mice randomly sampled from each line and recorded the genetic sex of each mouse. Keep in mind! Longer tibias have relation with longer legs.

USE SALT (a) After collecting the data, the research group calculates a 95% confidence interval to estimate the difference in population means. In this case, what is the population?
