MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The systolic blood pressure (given in millimeters) of males has an approximately normal distribution with mean, # = 125 and standard deviation o = 12. (a) Calculate the z-scores for the male systolic blood pressures 120 and 130 millimeters. (Round your answers to two decimal places.) 120 mm Z = 130 mm Z = (b) If a male friend of yours said he thought his systolic blood pressure was 2.5 standard deviations below the mean, but that he believed his blood pressure was between 120 and 130 millimeters, what would you say to him? (Enter your numerical answer to the nearest whole number.) He is | correct * ) because 2.5 standard deviations below the mean would give him a blood pressure reading of millimeters, which is |below the range of 120 to 130 millimeters.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You may need to use the appropriate appendix table or technology to answer this question. An experiment with a probability of success given as 0.30 is repeated 90 times. Use the normal distribution to approximate the binomial distribution, and find the probability the experiment will have at most 35 successes. (Round your answer to four decimal places.)
