Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury, for a sample of 7 adults. The following table presents the results.

Sociology 381L Name Estimation Ouiz There has ben a great deal of discussion about global warming in recent vears, In 2006, the Pew Rescarch Center conducted a survey of 1,501 Americans to assess their opinion of global warming. The data show 615 respondents of the 1,501 surveyed felt global warming is a very serious problem. 615 - 0.409 1501 a. Estimate the proportion of all adult Americans who felt global warming is a very serious problem at the 95% confidence interval. b. Estimate the proportion of all adult Americans who felt global warming is a very serious problem at the 99% confidence interval. If you were going to write a report on this poll result, would you prefer to use the 99% or 95% confidence interval? Explain why.
