Suppose the population standard deviation is standard deviation "sigma"=7, an SRS of n=45 is obtained, and the confidence level is chosen to be 95%. What is the margin of error for estimating a mean "mu" ?
A random sample of 16 men was selected from the population of ISU students. The sample's average BMI value was 22.5 with a standard deviation of 4.8. Create a 99% confidence interval for the mean of the population of male student. I DFocus W
The mean blood sodium concentration of these 38 cases was 115 mmol1, with standard deviation of 12 mmoll. Assuming that blood sodium concentration is normally distributed what is the 95% confidence interval within which the mean of the total population of such cases may be expected to lie? (Table value = 1.96)
A random sample of 100 components is drawn from a population size of 1546. Assume that the population standard deviation is 2.93 mm and the mean measurement of the components in the sample is 67.45mm with. Determine the 95% confidence intervals for an estimate of the mean of the population.
A simple random sample from a population with a normal distribution of 97 body temperatures has x=98.20°F and s=0.63°F. Construct a 99% confidence interval estimate of the standard deviation of body temperature of all healthy humans.
In a random sample of 8 people, the mean commute time to work was 34.5 minutes and the standard deviation was 7.3 minutes. A 98% confidence interval using the t-distribution was calculated to be (26.8,42.2). After researching commute times to work, it was found that the population standard deviation is 8.7 minutes. Find the margin of error and construct a 98% confidence interval using the standard normal distribution with the appropriate calculations for a standard deviation that is known. Compare the results.
