QUESTION 3 5points SaveAnswer You have measured the systolic blood pressure of a random sample of 30 employees of a company. A 95% confidence interval for the mean systolic blood pressure for the employees is computed to be (122, 138). Which of the following statements gives a valid interpretation of this interval? 0 95% of the sample of employees has a systolic blood pressure between 122 and 138. O 95 % of the employees in the company have a systolic blood pressure between 122 and 138. Q If the sampling procedure were repeated 100 times, then approximately 95 of the sample means would be between 122 and 138. If the sampling procedure were repeated 100 times, then approximately 95 of the 0 resulting 100 confidence intervals would contain the true mean systolic blood pressure for all employees of the company. 0 We are 95% confident the sample mean is between 122 and 138.
