Give three examples of complex access extrication: 

List common signs & symptoms of epiglottitis: 

Suppose in the previous problem the researcher had used larger samples to create the sampling distribution, such as samples of N = 100, use the drop-down options below to indicate what would happen to the shape, mean, and standard deviation of the sampling distribution of the mean. (1) The shape of the sampling distribution of the mean would . (2) The mean of the sampling distribution of the mean would . (3) The standard deviation of the sampling distribution of the mean would .

**To receive credit for the t-test problem: Sign and date your scratch paper with your hand calculations. Then take a picture of your hand calculations (make sure you include the formulas used and all work). Make sure the images are clear enough for me to see your work. If I can’t see your work, no credit will be given for the hand calculations. If you have more than one image, paste the pictures into either a single Word document (.doc or .docx) or pdf and then upload the file here.

Use the scores below to calculate the observed t-test score to test the prediction that the students study the recommended minimum of 15 hours a week. 22 28 12 16 23 17 15 8 29 26 **Report your final answer to 4 decimal places. **To receive credit for this problem you need to submit a picture of your hand calculations. The picture should show the formulas you used and your hand calculations, including the intermediate steps.

The American Heart Association recommends people get at least 150 minutes of moderate-intensity aerobic activity every week. 150 minutes a week equals 5 days of exercise for 30 minutes. To determine whether PSYC-330 students get the recommended amount of exercise, at the start of the semester students were asked, In a typical week, approximately how many days do you exercise 30 or more minutes? Responses ranged from 0 to 7 days. Below are the results from a one sample t-test that compares the answers given by PSYC-330 students with the recommended 5 days of exercise for 30 minutes. Use the SPSS output tables below, to select the statements that accurately describe the results of this study. Select all statements that are true. One-Sample Statistics   N Mean Std. Deviation Std.

A car manufacturer claims that their new car batteries will last 7 years. A group of concerned citizens argues that the batteries do not last as long as the manufacturer claims. To investigate the citizens’ claim, the car manufacturer surveys 20 random car owners and found the average battery lasted 6.89 years with a standard deviation of .25. Fill-in: If the car manufacturer wants to show the batteries do last 7 years they should run a one-sample test.

For each statement below, indicate whether the statement describes a population distribution, sampling distribution of the mean, both distributions, or neither distribution. -It is a distribution of raw scores (X): -The mean of the distribution equals mu (

Based on the results, what is the correct p-value for the problem?
