  1. You have measured the systolic blood pressure of a random sample of 25 students at KU. A 95% confidence interval for the mean systolic pressure for the students is computed to be (122, 138). Which of the followings statements gives a valid interpretation of the interval?

  1. About 95% of the sample of students have systolic blood pressure between 122 and 138

  1. About 95% of the students have a systolic blood pressure between 122 and 138

  1. If the sampling procedure were repeated many times, then approximately 95% of the sample means would be between 122 and 138

  1. The probability that the sample mean falls between 122 and 138 is 0.95

The systolic blood pressure of 16 students was measured before a test. The blood pressure from this sample averaged 165, with a standard deviation of 40. a) Compute the approximate 95% confidence interval for mean systolic blood pressure, and make a sketch illustrating these confidence intervals b) If a mean blood pressure above 130 is considered “stressed”, what do your calculations show regarding the probability that the observed mean is above the “stressed” level.
