Week 2: Frequency distributions and graphs; Data description Using the data set that you identified in week 1, use Excel to find the following descriptive statistics for the price data. Descriptive statistics: Mean Median Standard Deviation Use these summary statistics to make two conclusions or observations about the typical vehicle in the sample. One conclusion must relate to the measure of center (mean/median) and one to the variability (standard deviation) of the vehicles. Next,...

W4: The normal distribution I and II Recall the car data set you identified in Week 2. We know that this data set is normally distributed using the mean and SD you calculated. (Be sure you use the numbers without the supercar outlier) 1-For the next 4 cars that are sampled, what is the probability that the price will be less than$500 dollars below the mean? Make sure you interpret your results.

Using the data set you collected in Week 1, excluding the super car outlier, you should have calculated the mean and standard deviation during Week 2 for price data. Along with finding a p and q from Week 3. Using this information, calculate two 95% confidence intervals. For the first interval you need to calculate a T-confidence interval for the sample population. ........CONTI...........

How will you use the information in the future? This is your opportunity to consider and then share how you will employ the knowledge that you have gained during our course.

W3: Probability and counting rules; Discrete probability distributions Recall the car data set you identified in Week 2. You will want to calculate the average for your data set. (Be sure you use the numbers without the supercar outlier) Once you have the average count how many of your data points fall below the average. You will take that number and divide it by 10. This will be your p or "success" in your problem. Once you have p, calculate q. If you were to find another random sample of...
