Question Hannah has recently purchased a blood pressure monitor. Suppose… Hannah has recently purchased a blood pressure monitor. Suppose Hannah’s blood pressure reading (in mmHg) on any given day, is normally distributed with an unknown mean and variance^2=31.36. Assume that these readings are independent of day to day. Hannah records her blood pressure every day and randomly selects 50 of her previous blood pressure readings. Of these readings, Hannah calculated the sum of all the readings to be 6118.16 and 32 of them were less than 124.74. a.Using the sample data, test whether the true proportion of Hannah’s blood pressure readings that are less than 124.74 is less than 0.67. Clearly state your hypotheses and use a significance level of alpha=5%. b.Using the sample data, test whether is equal to 122. Clearly state your hypotheses and use a significance level of alpha=5%. c.Calculate the probability of making a type II error for the test in part B at a significance level of alpha=5%, if the true value of mean(u) is 121.3. d.Hannah decides eating vegetables might be good for her blood pressure. On any day on which her blood pressure is below the 67th percentile, the number of vegetables Hannah eats, from among a choice of 5 carrots, will be a binomial random variable with success probability 0.41. On any day on which her blood pressure is above the 67th percentile, the number of vegetables Hannah eats, from among a choice of 7 radishes, will be a binomial random variable with success probability 0.72. Find the probability that Hannah eats 3 vegetables today. Please provide Calculation: Math Statistics and Probability STAT 7055 Share QuestionEmailCopy link Comments (0)
