Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence interval of (4.1.5.3) when estimating the mean height (in centimeters) of a sample of seedlings. The estimated margin of error is The sample mean is
1. Use the confidence interval to find the estimated margin of error. Then find the sample mean. A biologist reports a confidence interval of (4.0, 4.8) when estimating the mean height (in centimeters) of a sample of seedlings. 2. In a random sample of 26 people, the mean commute time to work was 32.2 minutes and the standard deviation was 7.1 minutes. Assume the population is normally distributed and use a t-distribution to construct a 80% confidence interval for the...
