systolic blood pressure levels above 120 mm hg are considered to be high. for the 100 systolic blood pressure levels listed in the accompanying data set, the mean is 122.96000 mm hg and the standard deviation is 15.64371mm hg. assume that a simple random sample has been selected. use a 0.01 significancd level to test the claim that sample is from a population with a mean greater than 120 mm hg.

Blood pressure is a measure of the blood force against the walls of the arteries. Blood pressure that is consistently more than 140/90 mm Hg is considered high, but for people with diabetes, 130/80 mm Hg is considered high. Normal blood pressure is below 120/80 mm Hg. The larger value represents the pressure when the heart contracts and pushes blood out (systolic), and the smaller value is the lowest pressure when the heart relaxes between beats (diastolic). Consider a population...

A data set lists full IQ scores for a random sample of subjects with low lead levels in their blood and another random sample of subjects with high lead levels in their blood. The statistics are summarized below. Use a 0.05 significance level to test the claim that the mean IQ score of people with low lead levels is higher than the mean IQ score of people with high lead levels. Low Blood Lead Level: n = 77 x =...
When 14 different second-year medical students measured by the systolic blood pressure of the same person,...
When 14 different second-year medical students measured by the systolic blood pressure of the same person, they obtained the results listed below (in mmHg). Assuming that the population standard deviation is known to be 15 mmHg, use a 0.05 significance level to test the claim that the mean blood pressure level is less than 140 mmHg. Hyper- tension is defined to be a blood pressure level that is too high because it is 140 mmHg or greater. Assume the blood...

When subjects were treated with a drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken. Results are given in the table below. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Using a 0.05 significance level, is there sufficient evidence to support the claim that the drug is effective in lowering systolic blood pressure? Before: 188, 210, 157,...

Assume that a simple random sample has been selected from a normally distributed population and test the given claim. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. In a manual on how to have a number one song, it is stated that a song must be no longer than 210 seconds. A simple random sample of 40 current hit songs results in a mean length of 228.9 sec and...

The accompanying data table lists the magnitudes of 50 earthquakes measured on the Richter scale. Test the claim that the population of earthquakes has a mean magnitude greater than 1.00. Use a 0.01 significance level. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, and conclusion for the test. Assume this is a simple random sample.

Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a significance level to test for a difference between the measurements from the two arms. What can be concluded? right arm: 148, 139, 121, 129, 129 left arm: 182, 173, 189, 150, 147 In this example, is...

1. Park officials make predictions of times to the next eruptiom of a particular geyser, and collect data for the errora (minutes) in those predictions. The display from technology available below results from using the prediction errors to test the claim that the mean prediction error is equal to zero. Comment on the accuracy of the predictions. Use a 0.05 significance level. Identify the null and alternative hypothesis, test statistic, and P-Value. 2. In a test of the effectiveness kf...
