help for those 2 pleade with the step thank you Given the histogram shown below, what is the relative frequency of shrubs equal to or shorter than 1 m in height in this sample? Give your answer as a value between 0 and 1, to 1 decimal place. 0.8- 0.6- 0.0- 0.0 0.5 1.0 1.5 2.0 Tree height (m) Histogram of trees by height in a sample of 500 trees. Binwidth = 0.5 m. Answer: 0.002 A pharmaceutical company runs a trial of a drug designed to reduce high blood pressure on a population of people with an average systolic blood pressure of of 120 mm Hg, and a standard deviation of 20 mm Hg. The company measures blood pressure once for 200 trial subjects, and only gives the drug to 30 subjects with blood pressure measured above 140 mm Hg. They do not give the drug to any of the remaining subjects. If the drug is not actually effective at reducing blood pressure, how would you predict the blood pressure of the subjects treated with the drug to change on average when measured again one month later? Select one: a. The treated subjects will have higher blood pressure on average in the second measurement Pb. The treated subjects will have approximately the same blood pressure on average in the second measurement C. The treated subjects will have lower blood pressure on average in the second measurement Density of observations (1/m)
