Question

Exercises Present the results and solutions of the problems in a document, similar to that of the examples portion above. Copy and paste the plots, the function may be hand written but the rest should be word processed. You may print the plots, however, it is suggested that you copy and paste into your solution word document. To include MINITAB plots in MSword document: right click in the gray area of the figure window, select Copy Graph then paste into a MSword document along with your writeup. Once you have the figure irn the document you can resize it to fit your display preferences, see the examples portions for samples of display ideas. Do not copy and paste screen shots into your report Instead, copy and paste the actual MINITAB plots or appropriate portions of session window results into the report. You must provide a printout of the MINITAB version of the box plot, with the 5 number summary values, outliers and whisker ends labeled. MINITAB does not really label the plot so you may wish to label the box plot on your hardcopy of the document to be submitted or do so in msword. e Apollo space program lasted from 1967 until 1972 and included 13 missions. The missions lasted from as little as 7 hours to as long as 301 hours. The duration of ea flight is listed below 1) Th ch [ー9-一ー1951 2411301121612601_7 1244--1921147 | 10 | 295 | 142 | i. Determine the descriptive statistics for the data. Identify the 5 number summary Sketch the box plot for the data set using MINITAB and address the questions below Copy and paste the plot into your answer document and label the box plot on your hardcopy of the document to turn in (MINITAB does not really label the plot) Is the data skewed? (yes or no) If so, in which direction? (left skewed or right skewed) Explain your responses. ii. ii Create the Dotplot in MINITAB. Discuss any new observations of the data that the Dotplot brings out. 2) The national muffler company claims they will change your muffler in less than 3 minutes.

Answer 1

1. (i)

Descriptive Statistics: Duration of flight

Variable Minimum Q1 Median Q3 Maximum
Duration of flight 7.0 76.0 195.0 252.0 301.0

(ii)

Boxplot of Duration of flight 300 250 E 200 c 150 100 ให้)

Since from box plot we observed that Third quartile-2nd quartile<2nd quartile-First quartile so the data is positively(right) skewed.

(iii)

Dotplot of Duration of flight 40 80 120 160 200 240 280 Duration of flight

From dot plot it is observed that 7,9,10 are outliers.

2. i.

Descriptive Statistics: The no. of minutes

Variable Minimum Q1 Median Q3 Maximum
The no. of minutes 10.00 15.75 23.50 29.25 44.00

ii.

Since from box plot we observed that Third quartile-2nd quartile<2nd quartile-First quartile so the data is positively(right) skewed.

iii.

Dotplot of The no. of minutes 10 15 20 25 30 35 40 45 The no. of minutes

rom dot plot it is observed that 44 is an outlier.
