You may need to use the appropriate technology to answer this question. We want to test whether or not the addition of 3 variables to a model will be statistically significant. You are given the following information based on a sample of 25 observations. y = 62.480 - 1.838x₁ + 25.660x₂ SSE = 745; SSR = 596 The model was also estimated including the 3 variables. The results are: ý = 59.220 – 1.766x, + 25.635xy + 16.239Xg + 15.296xạ − 18.729×s SSE = 540; SSR = 801 (a) State the null and alternative hypotheses. O Ho: One or more of the parameters is not equal to zero. H₂: B3 =B4=B5 O Ho: B₁ = B₂= P3=B4 =B₁ = 0 H: One or more of the parameters is not equal to zero. O Ho: One or more of the parameters is not equal to zero. H₂: B₁ B₂ B3 = P4=B5 = 0 Ho: B3 B4 =B₁ = 0 H: One or more of the parameters is not equal to zero. (b) Test the null hypothesis at the 5% level of significance. Find the value of the test statistic. (Round your answer to two decimal places.) 5.64 Find the p-value. (Round your answer to three decimal places.) p-value = 091 x Is the addition of the three independent variables significant? Do not reject Ho. We conclude that the addition of the three independent variables is not statistically significant. O Reject Ho. We conclude that the addition of the three independent variables is statistically significant. Reject H. clude that the addition of the three independent variables is not statistically signi cant

Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 130 to 190 cm and weights of 41 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x = 167.53 cm, y 81.32 kg, r 0.259, P-value 0.009, and y = 106+ 1.09x. Find the best predicted value of y (weight) given an adult male who is 181 cm tall. Use a 0.10 significance lev. The best predicted value of y for an adult male who is 181 cm tall is kg. (Round to two decimal places as needed.)

Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 139 to 194 cm and weights of 39 to 150 kg. Let the predictor variable x be the first variable given. The 100 paired measurements yield x= 167.63 cm, y = 81.47 kg, r=0.106, P-value = 0.294, and y = - 108 + 1.04x. Find the best predicted value of y (weight) given an adult male who is 172 cm tall. Use a 0.05 significance level. The best predicted value of y for an adult male who is 172 cm tall is kg. (Round to two decimal places as needed.)

A random sample of n = 25 students in Gwinnett County schools were chosen to participate in a study about remote / digital study. Of the 25 students, 20 reported the Google Classroom provides the best access to digital content. %3D Which statement best describes the population and true parameter of this scenario? O The population is all students in Gwinnett County school; the parameter is the proportion of students that believe Google Classroom provides the best access to digital content The population is all students who participated in the remote / digital learning in Gwinnett County; the parameter is reported proportion of students that believe Google Classroom provides the best access to digital content The population is all students who participated in the remote / digital learning3B the parameter is the true proportion of students that believe Google Classroom provides the best access to digital content O The population is the 25 students who participated in the remote / digital…
