1. In an Economics textbook, the following information is given: TSS=437 andRSS-291. As a student of Econometrics, calculate the ESS and the R-squared.A. ESS-437 and R-squared=0.789B. ESS=146 and R-squared=0.334C. ESS=250 and R-squared=0.28TSSD. ESS=291 and R-squared=8.3342. What can you say about the above R-squared figure in question one?A. The TSS means that 437 variations in the dependent variables are explained byregressorsB. 40% of the regression power is explained by the error term.C. 33.4% variations in the dependent variable are explained by the independentvariable(s)D. The independent variables in the model are significant. 1463. The regression model includes a random error or disturbance term for a varietyof reasons. Which of the following is not one of them?A. Measurement errors in the observed variables.B. To capture unobserved omitted relevant influences on y.VSS=RSt°C. A linear functional form may only be an approximation.D. To capture unobserved omitted variables which are irrelevant to y.R = ESP

Shelia’s doctor is concerned that she may suffer from gestational diabetes (high blood glucose levels during pregnancy). There is variation both in the actual glucose level and in the blood test that measures the level. A patient is classified as having gestational diabetes if her glucose level is above 136 milligrams per deciliter (mg/dl) one hour after ingesting a sugary drink. Shelia’s measured glucose level one hour after the sugary drink varies according to the Normal distribution with μ = 125 mg/dl and σ = 11 mg/dl. a)What are the mean and standard deviation of the distribution of sample proportion if measurements are made instead on 40 separate days? b)If measurements are made on 40 separate days and the mean result is compared with the criterion 140 mg/dl, what is the probability that Shelia is diagnosed as having gestational diabetes? c)Let’s consider what could happen if we took 40 separate measurements from Shelia. What is the blood glucose level L such that the probability…

Solve all problems using a chi square analysis. You must use statistics to support your answers. 1. Azookeeper hypothesizes that changing the intensity of the light in the primate exhibits will reduce the amount of aggression between the baboons. In exhibit A, with a lower light intensity, he observes 36 incidences of aggression over a one-month period. In exhibit B, with normal lights, he observes 42 incidences of aggression. Should he support or reject his hypothesis? Observed Expected (o-e)/e (6-42)^2/e I X=? Degrees of freedom = 1 Critical value ?

Q1. A study was conducted to investigate the relationship between premature birth and mental development at 12 months. The infant's birth weight was used as an index of prematurity. At age 12 months, the child's mental development was recorded. The results are shown below (the weights are in pounds): Birth 4 6 7 8 Weight(x) Developmental 85 Quotients(y) 88 87 94 96 Summary: n = 5, £x=30, £x² = 190, Ey= 450, Ey² = 40590, Exy = 2728 . a. Find the least square prediction equation, y on x. b. Obtain a 95% confidence interval for the average value of y when x 6.5 (i.e., a C.I. for E(y|x= 6.5)). c. Obtain the coefficient of correlation (r) and interpret the result. d. Test the hypothesis that H, :p= 0 vs. H, : p0. Use a =0.05.

Q1. A psychologist conducted a study on the relationship between introversion and shyness. The values are results for scales of introversion and shyness. High positive scores on each scale indicate high introversion or shyness; and high negative scores indicate low introversion or shyness. Data collected from 10 people as follows: Introversion 4 -7 -1 0 6 7 -4 -9 -5 8 Shyness 11 -7 -1 -3 0 7 -1 -8 -1 5 a) Compute the correlation coefficient relating introversion and shyness scores. b) Find the regression equation which predicts introversion from shyness. c) What introversion score would you predict from a shyness score of 7?
