Internet Browsers Recently, the top web browser had 51.11% of the market. In a random sample of 225 people, what is the probability that fewer than 104 did not use the top web browser? Round the final answer to at least 4 decimal places and intermediate z-value calculations to 2 decimal places. P(X<104)= Life Expectancies in a study of the life expectancy of 500 people in a certain geographic region, the mean age at death was 72.0 years and the standard deviation was 5.3 years. If a sample of 50 people from this region is selected, find the probability that the mean life expectancy will be less than 70.5 years. Round intermediate z-value calculations to 2 decimal places and round the final answer to at least 4 decimal places. PX 10.5) - A Systolic Blood Pressure Assume that the mean systolic blood pressure of normal adults is 120 millimeters of mercury (mm Hg) and the standard deviation is 5.6. Assume the variable is normally distributed. Round the answers to at least 4 decimal places and intermediate z-value calculations to 2 decimal places. Part 1 of 3 If an individual is selected, find the probability that the individual's pressure will be between 117.1 and 120 mm Hg. P(117.1 < X<120) 0.1985 Part: 1/31 Part 2 of 3 If a sample of 24 adults is randomly selected, find the probability that the sample mean will be between 117.1 and 120 mm Hg. Assume that the sample is taken from a large population and the correction factor can be ignored. P(117.1 <<120) - x 5 Internet Browsers Recently, the top web browser had 51.11% of the market.
