In a hospital the average time that a patient will wait to enter a clinic is normally distributed with a mean of 20 minutes. A random sample of 10 patients revealed the following waiting time: 21 19 18 18 20 22 23 25 17 20 Given the sample standard deviation S = 2.5 Assume that the researcher wants to test whether the mean time that a patient will wait is more than 20 minutes using a level of significance of 0.01.

A major newspaper (that rhymes with Small Street Journal) reported an average household income for its subscribers is $119,155. Assume this estimate of the mean household income is based on a sample of 80 subscribers, and, based on past studies, the population standard deviation is known to be sigma=$30,000. Construct a 95% confidence interval for the population mean. Group of answer choices $60,356 - $177,954 $118,420 - $119,890 $112,447 - $125,863 $112,581 - $125,729

A lumber company is making boards that are 2701.02701.0 millimeters tall. If the boards are too long they must be trimmed, and if they are too short they cannot be used. A sample of 2222 boards is made, and it is found that they have a mean of 2703.92703.9 millimeters with a variance of 100.00100.00. Is there evidence at the 0.10.1 level that the boards are either too long or too short? Assume the population distribution is approximately normal. Is there sufficient evidence to support the claim that the boards are either too long or too short?
Air Quality Index is a way to measure particle pollution in the air. An index between 0 and 50 is considered good; between 51 and 100 is moderate; more 100 is considered unhealthy for sensitive groups and others. A recent sample data of air quality index values for Pomona in Southern California provided the following data. 50, 52, 59, 56, 58 What are the sample mean, sample variance and the sample standard deviation?
Suppose a researcher is interested in a new treatment plan for increasing CD4 cell count in immune-compromised patients with HIV. In order to investigate the new drug, the researcher gathers a group of 48 individuals with a mean CD4 count of 317 cells/mm3 after treatment with a standard deviation of 24.6. Test the hypothesis that the mean CD4 count has increased above the goal of 275 cells/mm3. Write out your hypotheses and correctly interpret your pvalue. (Use an alpha level of 0.01)
All patients admitted to a particular hospital can be released on the same day or kept overnight for observation. In a sample of 2550 patients, 1020 were kept overnight for observation a) What is the point estimate p for the proportion of all patients kept overnight for observation? b) Construct a 99% confidence interval for the proportion of all patients kept overnight for observation.
Police recorded the average speed of cars driving on a busy street by a school. For a sample of 16 speeds, it was determined that the average amount over the speed limit for the 16 speeds was 11.4 mph with a standard deviation of 6 mph. The 90% confidence interval estimate for this sample is 8.77 mph to 14.03 mph. a) What is the margin of error for this problem? b) What size sample is needed to reduce the margin of error to no more than + 17 a) The margin of error isOmph.
The nutrition label for Oriental Spice Sauce states that one package of sauce has 1030 milligrams of sodium. To determine if the label is accurate, the FDA randomly selects 130 packages of Oriental Spice Sauce and determines the sodium content. The sample has an average of 1000.15 milligrams of sodium per package with a sample standard deviation of 271.69 milligrams. Step 1 of 2 : Calculate a 95% confidence interval for the mean sodium content in Oriental Spice Sauce. Round your answers to two decimal places.
A cereal company checks the weight of its breakfast cereal by randomly checking 62 of the boxes. This particular brand is packed in 20-ounce boxes. Suppose that a particular random sample of 62 boxes results in a mean weight of 20.04 ounces. How often will the sample mean be this high, or higher if u = 20 and σ = 0.10 4
