How do I go about this practice exercise about the normal distribution.

Collect the Data: Measure the length of your pinkie finger (in cm.) Now, go around and record the lengths of 30 people. Round to the nearest 0.5 cm. 2 2.3 2.25 2. 4 2.5 2.S 2.25 2.5 2.3 2.S 2. S 2. S 2.5 2. 4 2.4 2.3 2 . 6 2.3 Construct a histogram. Make 5 -6 intervals. Sketch the graph using a ruler and pencil. Scale the axes. Frequency Length of Finger Draw a smooth curve through the top of the bars of the histogram. Use 1 - 2 complete sentences to describe the general shape of the curve. (Keep it simple. Does the graph go straight across, does it have a V shape, does it have a hump in the middle or at either end, etc.?) Calculate: the sample mean = the sample std. deviation = Math 119 Chapter 6 Assignment 1 Analyze the Data Using your sample mean, sample standard deviation, and histogram to help, what was the approximate theoretical distribution of the data from Part !? . X - How does the histogram help you arrive at the approximate distribution? Describe the Data: Using the data in Part I (Hint: order the data): The IQR goes from to . IQR = . The 15th percentile is The 85" percentile is The median is The empirical probability that a randomly chosen pinkie length is more than 6.5 cm = . Explain the meaning of the 85th percentile of this data. Theoretical Distribution: Using the theoretical distribution in Part II: The IQR goes from to . IQR = . The 15th percentile is The 85# percentile is The median is . The theoretical probability that a randomly chosen pinkie length is more than 6.5 cm = . Explain the meaning of the 85th percentile of this distribution
