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 forpricedata.Along with finding apandqfrom 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.You have the mean, standard deviation and the sample size, all you have left to find is the T-critical value and you can calculate the interval.For the second interval calculate a proportion confidence interval using the proportion of the number of cars that fall below the average.You have thep,q, andn, all that is left is calculating a Z-critical value,
