Mr. Friend noticed that meetings tended to start late when there were a lot of people in attendance and decided to study that relationship. He collecting data on the number of people who were attending each meeting and the number of minutes late that the meeting started. He noticed there was one point that seemed unusual, so he removed it from the data set. What is true about the point that was removed?   a. the point is not unusualb. It is an influential observationc. It has the largest residuald. The slope changes little when the point is removedSelected:e. The correlation is lower with the removal of the point

An instructor for a test preparation course claims that the course will improve the test scores of students. The table shows the critical reading scores for 14 students the first two times they took the test. Before taking the test for the second time, the students took the instructor's course to try to improve their critical reading test scores. At a = 0.01, is there enough evidence to support the instructor's claim? Complete parts (a) through (f).

You are told there is a negative relationship between study time and test performance.  What would be the conclusion you can state about the two variables (want you to state actual verbal conclusion using variables given).

Dr. Peart randomly assigns some children to two separate groups. One group of children watches a video of an adult "beating" a doll. The other group watches a video of the same adult playing with the doll. After the video, each child is given a doll and the researchers observed what they did with the doll. In this case, the independent variable is:  i. What is the independent variable and dependent variable in this study? Name the conditions in the independent variable.  ii. If Dr. Peart wants to have 10 children in each condition, what is the total number of kids that she needs?

A test was given to a statistics class. Results for each gender and for one student in each gender are given. From the information provided, determine which student received a relatively higher grade. The female scored a 78 with μ=84 and σ=3. The male scored a 80 with μ=86 and σ=2. The female student has a higher relative grade than the male student The male student has a higher relative grade than the female student Both students have the same relative grade Not enough information to determine
