An estimator for parameter v is consistent if E(v) is close to v when sample size is increased. Instruction TRUE or FALSE ?

In a regression line of Y on X, the variable Y is know as random variable dependent variable qualitative variable independent variable

The mean mark on a state-administered mathematics exam by a 10th grade class in Smalltown, Wisconsin, was 95%, while the mean mark on the same exam by 10th grade students in the entire state of Wisconsin was reported to be only 78%. This suggests that the mean can be __________.  a a parameter or a statistic b a parameter only c a statistic only d neither a parameter nor a statistic

Use correlation coefficients to determine which of the given sets of data is best fit by its associated regression line and which is fit worst. a. ((6, 8), (3, 14), (7, 6)) b. ((5, 6), (6,5), (7, 6)) c. ((5, 5), (10, 0), (7, 7.1)) Select the data set with the best fit. O ((6, 8), (3, 14), (7, 6)) ((5, 6), (6, 5), (7, 6)) ((5, 5), (10, 0), (7, 7.1)) Select the data set with the worst fit. O ((6, 8), (3, 14), (7, 6)) ((5, 6), (6, 5), (7, 6)) ((5, 5), (10, 0), (7, 7.1)) Is it a perfect fit for any of the data sets? Yes No

True or false

The correlation coefficient for this relationship between the X variable and the Y variable would probably be quite high Select one: True False X-Axis Match the letter of the graph to the type of relationship it depicts. Non-linear relationship Choose... strong positive correlation Choose... (b) (c) weak or no relationship, close to 0 correlation Choose... Choose strong negative correlation Choose.. uniform distribution of the Y variable in relation to X (d) (e) (f) -Axis

Consider a regression with two variables, in which X1i is the variable of interest and X2i is the control variable. The zero conditional mean assumption requires Group of answer choices E(ui|X1i) = E(ui|X2i) E(ui|X1i, X2i) = E(ui|X1i) E(ui|X1i, X2i) = 0 E(ui) = E(ui|X2i)

Paragraph Styles 4. Reading is fundamental to a teenager's ability to perform well in school. Assume a researcher is interested in the ability of the number of books read over the summer to predict ACT Reading scores. Using a random sample of 10 random high school students the researchers recorded the number of books read over the summer and the students' ACT Reading scores. Books read over summer (x) ACT Reading score (y) 16 19 17 4 25 4 21 24 6. 21 8 24 27 10 22 Answer the following questions using the SPSS regression analysis OUTPUT (given below): a. From the SPSS regression analysis OUTPUT (given below), write the regression line using the number of books read to predict ACT Reading score. b. What is the predicted ACT Reading score when 5 books are read? C. Does the number of books read significantly predicts ACT at a = 0.05? State your null and alternative hypotheses. d. How much variation in y is explained by this linear regression model? D Focus a IN
