The Iris Flower Data Set at https://en.wikipedia.org/wiki/Iris flower data set e consists of measurements taken from Iris flowers: the petal length and width and the sepal length and width were measured in centimeters (cm) and recorded for a lot of flowers. We are interested in being able to use the petal width to predict the petal length. Use the Excel output provided below to answer the Iris Flower questions that follow.

LORETTA STONE 0/20 Question 3 of 10, Step 1 of 4 Correct A state legislator wants to determine whether his voters' performance rating (0 - 100) has changed from last year to this year. The following table shows the legislator's performance from the same ten randomly selected voters for last year and this year. Use this data to find the 90 % confidence interval for the true difference between the population means. Assume that the populations of voters' performance ratings are normally distributed for both this year and last year. Rating (last year) 77 89 50 44 54 51 66 42 94 44 Rating (this year) 50 94 75 55 45 65 94 67 91 46 Copy Data Step 1 of 4: Find the point estimate for the population mean of the paired differences.
