The average wait time to see a doctor at the Walnut ER on a Monday afternoon is 12 minutes. Is the mean wait time less for women with small children? Wait times for 12 randomly selected women with small children are shown below. Assume that the distribution of the population is normal. 11, 11, 9, 12, 13, 11, 10, 10, 11, 12, 12, 11 What can be concluded at the the a -0.01 level of...

The amount of time that you have to wait before seeing the doctor in the doctor's office is normally distributed with a mean of 15.2 minutes and a standard deviation of 15.2 minutes. If you take a random sample of 64 patients, what is the probability that the average wait time is greater than 20 minutes?

A hospital was concerned about reducing its wait time. A targeted wait time goal of 25 minutes was set. After implementing an improvement framework and process, a sample of 351 patients showed the mean wait time was 23.15 minutes, with a standard deviation of 16.06 minutes. Complete parts (a) and (b) below. a. If you test the null hypothesis at the 0.10 level of significance, is there evidence that the population mean wait time is less than 25 minutes? State...

Samsung claims that the average wait time for a customer calling the Samsung Care support line is 175 seconds. A simple random sample of 45 customers was selected, and their average wait time was found to be 187 seconds. Assume the population standard deviation of wait time is 50 seconds. Is there enough evidence to conclude that the average wait time for a customer calling the Samsung Care support line is more than 175 seconds? Use α = 0.01. a)...

Using the current system, the mean wait time for people who call for technical support is 5 minutes. A new system was designed to reduce the mean wait time. A random sample of 400 calls produced a sample average of 4.650. The standard deviation of wait times is known to be 4. We want to know whether the new software changed the mean. 1. What is the null hypothesis and what is the alternative hypothesis? 2. What is the value...
