nercep ra 12} i tige score' prestige score of 722. What prestige value would you predict for a daughter whose father had a prestige score of 72? Compute the strength and direction of the relationships. Describe: Does the occupational prestige of a person impact their children? Does having a father with daughters have the same effect as having a father with sons? Summarize the impact for housing development for 12 [GER]. The residents completed a survey in which they reported how physically active senior citizens are and how many visitors they receive each week. Are these two variables related for the ten cases reported here? Find the least-squares regression line and compute the predicted number of visitors for a person whose level of activity was 18. What about a person who scored 10 on the level of activity? Level of Activity Number of Visitors Case unem #ycr ela 10 10 15 12 ; 10 Wediet Fable Jea€

A sample of 10 mothers and their first born daughters were asked their heights (in inches). The data were as follows Table of values for Mothers and Daughters heights Mother Daughter 67 67 69 71 67 68 65 65 66 66 62 61 66 67 63 62 61 59 66 66 2a) Using the heights of the mothers as the independent variable and the heights of the daughters as the dependent variable, determine the least squares line for these data. Round values to the nearest tenth. y = + x 2b) What is the value? Round to 4 decimal places 2c) Interpret in the context of the problem. [98.58] percent of the variation in the daughter's height can be explained by the least squares regression line. 2d) What is the r value for the equation? Round to the nearest hundredth. 2e) From r, we determine that there is a (weak/strong) (positive/negative) relationship between the mother's and daughter's heights.

A student of ICEF considers for her graduation thesis the hedonic price function for houses. The hedonic price refers to the implicit price of a house given certain attributes (e.g., the number of bedrooms). The data contains the sale price of 546 houses sold in the summer of 2017 in the Moscow region (in thousands of rubles) along with their important features. The following characteristics are available: the lot size of the property in square meters (lotsize), the number of bedrooms (bedrooms), the number of full bathrooms (bathrooms), and a dummy indicating the presence of air-conditioning (airco). Consider the following ordinary least squares results log(price)i = 9.894 + 0.400 log(lotsize)i + 0.078 bedroomsi + 0.096 bathroomsi + 0.212 aircoi n = 546 (1) (0.232) (0.028) (0.015) (0.023) (0.024) [0.233] [0.028] [0.017] [0.024] [0.023] The usual standard errors are in parentheses, the heteroskedasticity robust standard errors are in square brackets, and RSS measures the residual sum of squares.

Does the location of your seat in the classroom play a role in attendance or grade? 800 students in a physics course were randomly assigned to one of four groups. The 200 students in group 1 sat 0 to 4 meters from the front of the class, the 200 students in group 2 sat 4 to 6.5 meters from the front, the 200 students in group 3 sat 6.5 to 9 meters from the front, and the 200 students in group 4 sat 9 to 12 meters from the front. Complete parts (a) through (c). (a) For the first half of the semester, the attendance for the whole class averaged 76%. So, if there is no effect due to seat location, we would expect 78% of students in each group to attend. The data show the attendance history for each group. How many students in each group attended on average? Is there a significant difference among the groups in attendance patterns? Group Attendance 0.75 0.75 The number of students who attended in the first group was ______. The number of students who attended in the second group was ______. The number of students who attended in the third group was ______. The number of students who attended in the fourth group was ______.
