A random sample of 49 lunch customers was taken at a restaurant. The average amount of time the customers in the sample stayed in the restaurant was 45 minutes with a standard deviation of 14 minutes. a. Compute the standard error of the mean. b. Construct a 99% confidence interval for the true average amount of time customers spent in the restaurant. c. With a .99 probability, how large of a sample would have to be taken to provide a...

5. A random sample of 625 customers of the restaurant xyz revealed the average monthly expenses in the amount of € 43.50 with a standard deviation of 19.20. a) Assuming that the dining expenses are normally distributed, construct a 95% confidence interval for the population mean expenses among xyz consumers( keep 2 decimals in your answer) b) How confident are you that the estimated 43.50 will be within 1.50 of the population mean? c) What would your margin of error...

A simple random sample of 24 observations is derived from a normally distributed population with a known standard deviation of 7.8. [You may find it useful to reference the z table.] a. Is the condition that X−X− is normally distributed satisfied? Yes No b. Compute the margin of error with 99% confidence. (Round intermediate calculations to at least 4 decimal places. Round "z" value to 3 decimal places and final answer to 2 decimal places.) Margin error: ? c. Compute...

A random sample of size n=68 is taken from a finite population of size N=644 with mean y = 239 and variance o?. 325. [You may find it useful to reference the table.) 8-1. Is it necessary to apply the finite population correction factor? Yes No 0-2. Calculate the expected value and the standard error of the sample mean (Round "expected value to a whole number and standard error to 4 decimal places.) Answer is complete but not entirely correct....

random sample of air temperatures in December is taken from n 42cities in Minnesota. Temperature data is nown to be normally distributed. The historical average temperature in Minnesota in December is -8.5 and tandard deviation O=5. Use Table 1 Calculate the expected temperature value and the standard error for the sampling distribution of the sample mean (Negative values should be indicated by a minus sign. Round "expected value to 1 decimal place and "standard error" to 4 decimal places.) Expected...

A random sample of size n = 50 is taken from a population with mean μ = −9.5 and standard deviation σ = 2. [You may find it useful to reference the z table.] a. Calculate the expected value and the standard error for the sampling distribution of the sample mean. (Negative values should be indicated by a minus sign. Round "expected value" to 1 decimal place and "standard deviation" to 4 decimal places.) b. What is the probability that...

A quality control specialist for a restaurant chain takes a random sample of size 10 to check the amount of soda served in the 16 oz. serving size. The sample mean is 13.60 with a sample standard deviation of 1.54. Assume the underlying population is normally distributed. Find the 95% confidence interval for the true population mean for the amount of soda served. (Round your answers to two decimal places.)
