Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller.

Use the standard normal distribution to compare two other normal distributions. 25. Blood pressure is described by two numbers: systolic pressure and diastolic pressure (measured in mmHg, or millimeters of mercury). For example, a blood pressure of 120/80 denotes a systolic pressure of 120 mmHg and a diastolic pressure of 80 mmHg. A study of 625 persons ages 26 to 45 finds that their blood pressures are normally distributed. Their systolic pressure had a mean of 122 and a standard deviation of 14, and their diastolic pressure had a mean of 83 and a standard deviation of 9. Two study participants are randomly selected and their blood pressures are measured again. The first participant had a systolic reading of 99 mmHg, while the second had a diastolic reading of 70 mmHg. Which participant had the lower reading with regard to the study population? 26. Health experts often consider blood pressure to be elevated if systolic pressure is 140 or greater or the diastolic pressure is 90 or…
