the first quartile is 5 the third quartile is 8 find the IQR =
Why is L75 different than the Third Quartile? I can easily find
3rd Quartile using excel. I'm not sure how to find L75 though?
Thank you!!

Step 3 Next, find Q1. Recall that the first quartile, Q,, is the median of the lower half of the data. That is, the median of the data located below the Q2 position. Consider the ordered list of data values. The median, Q2, which was determined in the last step, has been underlined for clarity. 9, 12, 12, 13, 14, 14, 15, 16, 17 values to the left of the There are nine values in the whole data set, but...

95. 75% of all years have an FTES: a. at or below: b. at or above: 96. The population standard deviation = 97. What percent of the FTES were from 528.5 to 1447.5? How do you know? 98. What is the IQR? What does the IQR represent? 99. How many standard deviations away from the mean is the...
For the given set of stock market data you are required to perform statistical analysis of this data to find out the mean, the variance, the mode, the median, the third quartile and the first quartile for the full population using a Matlab program (or any other program). You are also asked to plot the histogram, time sequence diagram and boxplot of the whole data using Matlab (or any other program). 66.591 85.24 65.961 75.173 77.209 67.043 81.666 69.626 65.26...
Find the first quartile for a box plot of the following numbers: 11 13 15 18 21 22 25 26 30 35 42 45
Find the maximum of x in the bottom quartile. (Round your answer to four decimal places.) X ~ N(6, 7)
6) Remedy a) Find the upper quartile Qs and interpret specific to the problem. {8 pts The following is a sample of 20 November utility bills an dollars from a goal: 52.12,,%, 72, 74, 74, 76, 76, 76, 78, 78, 82, 84, 84, 86, 88, 92, 96, 110.
Find the maximum of x in the bottom quartile. (Round your answer to four decimal places.) X ~ N(7, 9)
WHAT IS THE SCORE IN THE LOWER QUARTILE (Q1)?
*****Hints: you should
recognize "lower quartile (Q1)" as the Lower 25% (LEFT tail area)
under the normal curve, then find the z-score, and calculate the
"x" using the z-score formula.
Problem 2: Note: For EACH of the following part, draw a normal curve, mark the x-axis accordingly. and highlight the corresponding areas. Round z-scores to the SECOND decimal place, and keep the ORIGINAL FOUR decimal places for the probability. The average...
