The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the
reduction in systolic blood pressure is 73.1 for a sample of size 29 and standard deviation 16.5. Estimate how
much the drug will lower a typical patient's systolic blood pressure (using a 99% confidence level). Assume the
data is from a normally distributed population.
Enter your answer as a tri-linear inequality accurate to three decimal places.

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
