value: 2.00 points The following stem-and-leaf chart from the MINITAB software shows the number of units produced per day in a factory 2 3 69 4 457 6 13 7 13 10 6 0133569 7 0236778 8 568 9 0015678 10 367 (Leave no cells blank, be certain to zero whenever required.) a. How many days were studied? b. How many observations are in the first class? c. What are the minimum value and the maximum value? The minimum i the maximum is d. List the actual values in the fourth row 60.61 63.63.65,66.69 61.63.63.60.65,66.69 60.62.64,65.65,66.69 60.61,61 63 65,66.69 e. How many observations are in the second row?Explanation / Answer
Solution:-
a) 33 (we count each leaf)
b) 2
c) Minimum value is 36, maximum value is 107.
d) (a) 60, 61, 63, 63, 65, 66, 69
e) 3 observations
f) 13 values are less than 70.
g) 13 values are 80 or more.
h) Median is the middle value, here total number of observations are 33, which is an odd number. Therefore, median is (n+1)/2th term.
That is, (33+1)/2th term = 17th term = 76
i) 17 terms are between 60 and 89, inclusive.
