Perform the required t-test for the slope of the regression line and state your conclusion. Applicants for a particular job, which involves extensive travel in Spanish-speaking countries, must take a proficiency test in Spanish. The sample data below were obtained in a study of the relationship between the numbers of years applicants have studied Spanish and their score on the test. At the 5% level of significance, do the data provide sufficient evidence to conclude that the slope of the regression line is not 0 and hence that number of years of study is useful as a predictor of score on the test? The regression analysis is given below. Dependent variable is: Score R squared = 83.0% s = 5.65138 with 10 - 2 = 8 degrees of freedom Variable Coeficient s.e. of Coeff t-ratio prob Constant 31.53333 6.360418 4.957745 0.00111 Number of Years 10.90476 1.744054 6.252538 0.000245 O Ho: B1 > 0 HA: B1 SO P-value = 0.000245 Support HA. At the 5% level of significance, the data provide sufficient evidence to conclude that the slope of the regression line is less than or equal to O and hence that number of years of study is useful as a predictor of score on the test. O Ho: B1 = 0 HA: B1 # 0 P-value = 0.000245 Do not reject Ho. At the 5% level of significance, the data does not provide sufficient evidence to conclude that the slope of the regression line is not 0. O Ho: B1 = 0 HA: B1 = 0 P-value = 0.00111 Reject Ho. At the 5% level of significance, the data provide sufficient evidence to conclude that the slope of the regression line is not 0 and hence that number of years of study is useful as a predictor of score on the test. O Ho: B1 = 0 HA: B1 0 P-value = 0.000245 Reject Ho. At the 5% level of significance, the data provide sufficient evidence to conclude that the slope of the regression line is not 0 and hence that number of years of study is useful as a predictor of score on the
