The mean is Round to two decimal places as needed.) The median is (Type an integer or a decimal.) What is the mode? Select the correct choice below and, if necessary,fill in the answer box to complete your choice 0 A. The mode(s) isare ! Type an integer or a decimal. Use a comma to separate answers as needed.) There is no mode for this data set. O B. b. Calculate the variance, standard deviation, range, and Z scores. Are there any outlers? Explain. The variance is (Round to four decimal places as needed.) The standard deviation is (Round to three decimal places as needed.) The range is (Type an integer or a decimal.) Compute the Z scores for the first five values. Data (3) 56 20 26 23 38 Z Score Round to two decimal places as needed.) Compute the Z scores for the next five values. Data (X) 41 Z Score 41 26 48Explanation / Answer
a)
mean = 438/13 = 33.6923
median = 38
The median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.
Ordering the data from least to greatest, we get:
7 20 22 23 26 26 38 41 41 44 46 48 56
So, the median is 38 .
A) mode are 26 and 41
The mode of a set of data is the value in the set that occurs most often.
Ordering the data from least to greatest, we get:
7 20 22 23 26 26 38 41 41 44 46 48 56
Since both 26 and 41 occur 2 times, the modes are 26 and 41 ( this data set is bimodal).
b)
variance =196.2308
sd = 14.0082
range = 49
.The range is the difference between the highest and lowest values in the data set.
Ordering the data from least to greatest, we get:
7 20 22 23 26 26 38 41 41 44 46 48 56
The lowest value is 7.
The highest value is 56.
The range = 56 - 7 = 49.
z = (X - mean)/sd = (X - 33.6923 )/14.0082
