Use the given confidence interval to find the margin of error and the sample mean. (6.19,8.33) The sample mean is The margin of error is (Type an integer or a decimal.) (Type an integer or a decimal.)
Virginia wants to estimate the percentage of students who live more than three miles from the school. She wants to create a 95% confidence interval which has a margin of error of at most 5%. How many students should be polled to create the confidence interval? z0.10 z0.05 z0.025 z0.01 z0.005 1.282 1.645 1.960 2.326 2.576 Use the table of values above.
Bert computes a 95% confidence interval for p and obtain the interval [0.600,0.700]. Bert boss says, Give me a 95% confidence interval for p. Calculate the answer for Bert.
The Pizza Shop wanted to determine what proportion of its customers ordered only cheese pizza. Out of 80 customers surveyed, 15 ordered cheese pizza. They want a 99% confidence interval of the true proportion of customers who order only cheese pizza. Which type of confidence interval should we use here? a confidence interval for the mean using a table value from the standard normal distribution. a confidence interval for the mean using a table value from the t distribution. a confidence interval for a proportion using a table value from the standard normal distribution. a confidence interval for proportion using a table value from the t distribution.
Use the given confidence interval to find the margin of error and the sample mean. (15.3,23.7) The sample mean is . (Type an integer or a decimal.) The margin of error is. (Type an integer or a decimal.)
) For each problem below, Decide whether it describes a confidence interval for a proportion or a confidence interval for a mean. Apply the correct formula to calculate the confidence interval in the format of an estimate + margin of error. During the 2016 season, Mark Williams played in 18 golf matches and used his driver club 126 times, hitting his drives an average of 278 yards per drive, with a standard deviation of 15 yards per drive. Calculate a 95% confidence interval for the distance he was able to hit his driver club in that season.
Use the given confidence interval to find the margin of error and the sample mean. (11.3,21.1) The sample mean is The margin of error is
Use the confidence interval to find the estimated margin of error. Then find the sample mean. A store manager reports a confidence interval of (46.7,78.3) when estimating the mean price (in dollars) for the population of textbooks. The estimated margin of error is (Type an integer or a decimal.) The sample mean is (Type an integer or a decimal.)
Use the confidence interval to find the estimated margin of error. Then find the sample mean. A store manager reports a confidence interval of (43.1,81.9) when estimating the mean price (in dollars) for the population of textbooks. The estimated margin of error is (Type an integer or a decimal.) The sample mean is (Type an integer or a decimal.)

Assume that the 95% confidence interval for mean=9 and standard devaition=20. For a particular data, the standardized value z = 2.73. We can say that: Select one: a. The data with standardized value 2.73 does not belong to the confidence interval and the value is less than the average. b. The data with standardized value 2.73 does not belong to the confidence interval and the value is greater than the average. c. Cannot interpret the z-value information provided. d. The data with standardized value 2.73 if it belongs to the confidence interval and the value is less than the average. e. The data with standardized value 2.73 if it belongs to the confidence interval and the value is greater than the average.
