The sample mean is Type an integer or a decimal.) Find the minimum sample size n needed to estimate μ for the given values of c. and E. cz 0.90, ơ 7.9, and E-2 Assume that a preliminary sample has at least 30 members. n-Round up to the nearest whole number )
Use the given confidence interval to find the margin of error and the sample proportion. (0.783,0.807)
Use the normal distribution to find a confidence interval for a proportion p given the relevant sample results. Give the best point estimate for p , the margin of error, and the confidence interval. Assume the results come from a random sample. A 95% confidence interval for the proportion of the population in Category A given that 18% of a sample of 450 are in Category A. Round your answer for the point estimate to two decimal places, and your...
Use the given confidence interval to find the margin of error and the sample mean. (14.6,23.8)
Use the t-distribution to find a confidence interval for a mean given the relevant sample results. Give the best point estimate for the margin of error, and the confidence interval. Assume the results come from a random sample from a population that is approximately normally distributed A 90% confidence interval for using the sample results T = 2.9.5 = 0.3, and n = 100 Round your answer for the point estimate to one decimal place, and your answers for the...
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...
