what is the 99% confidence interval?

TestScore = 567.2360 + (-6.3438) x CS, R" = 0.10, SER = 12.5 (22.2360) (2.3426) Construct a 95% confidence interval for B1, the regression slope coefficient. The 95% confidence interval for 1, the regression slope coefficient, is ( ). (Round your responses to two decimal places.) The t-statistic for the two-sided test of the null hypothesis Ho: B1 = 0 is (Round your response to four decimal places.) Note: Assume a normal distribution. The p-value for the two-sided test of the null hypothesis Ho: B1 = 0 is (Round your response to four decimal places.) Do you reject the null hypothesis at the 1% level? O A. Yes, because the p-value is less than 0.01. O B. No, because the p-value is greater than 0.01. O C. Yes, because the t-statistic is greater than 2.58. O D. Yes, because the t-statistic is less than 2.58. The p-value for the two-sided test of the null hypothesis Ho: B1 = - 6.1 is (Round your response to four decimal places.) Without doing any additional calculations, determine whether - 6.1 is contained in the 95% confidence interval for B1 . O A. Yes, - 6.1 is contained in the 95% confidence interval for By . O B. No, - 6.1 is not contained in the 95% confidence interval for By . The 99% confidence interval for Bo is ( ). (Round your responses to one decimal place.)
