hello cann someone please help me with these statistic questions thank you

1.

a. Obtain and interpret the quartiles. Determine the qua rtiles. 01= 660' 02= 1.300' 03 = 5623' (Type integers or decimals. Do not round.) Interpret the quartiles. Choose the correct answer below. * The quartiles suggest that 25% of the companies have capital spending less than 01. 25% have capital spending between 01 and 02. 25% have capital spending between 02 and 03, and 25% have capital spending more than 03. The quartiles suggest that 33% of the companies have capital spending less than 01. 33% of the companies have capital spending between 01 and 03, and 33% of the companies have capital spending more than 03. X The quartiles suggest that the average capital spending is 02. The quartiles suggest that all of the companies have capital spending between 01 and 03. b. Determine and interpret the interquartile range. The interquartile range is 4,963. (Type an integer or a decimal. Do not round.) Interpret the interquartile range. Choose the correct answer below. O A. The data span roughly the IQR. O B. The approximate difference between each quartile is the IQR. C. The capital spending in the middle 50% of companies spans roughly the IQR. O D. The average of the first quartile and the third quartile is the IQR. c. Find and interpret the five-number summary. Determine the five-number summary. 21 , 660 , 1,800 , 5,623 , 17,341 (Type integers or decimals. Do not round. Use ascending order.) Interpret the five-number summary. Choose the correct answer below.c. Find and interpret the venumber summary. Determine the fivenumber summary. 21'. 560'. 1300', 5.623', 1?.341' (Type integers or decimals. Do not round. Use ascending order.) Interpret the venumber summary. Choose the correct answer below. x The distance between the minimum and the rst quartile has the greatest variation. The distance between the first quartile and the median has the least variation. The distance between the third quartile and the maximum has the greatest variation. The distance between the median and the third quartile has the least variation. * The distance between the median and the third quartile and the distance between the third quartile and the maximum have more variation than the distance between the minimum and the rst quartile and the distance between the first quartile and the median. The distance between the minimum and the rst quartile and the distance between the first quartile and the median have more variation than the distance between the median and the third quartile and the distance between the third quartile and the maximum. cl. Identify potential outliers. if any. Choose the correct answer below and, if necessary. fill in the answer box to complete your choice. The potential outlier(s) is(are] 1?,341'. (Type an integer or a decimal. Do not round. Use a comma to separate answers as needed.) There are no potential outliers. 9. Obtain and interpret a boxplot. Construct the boxplot. Choose the correct graph below. V a a q q +% a l} . . D 18000 D 18000 Interpret the boxplot. Select all that apply. The amount of capital spending varies irom 21 to 17,341 thousand dollars. I The potential outlying observation falls far from the rest oi the data. The distribution of the data is roughly symmetric. A. B. C. Amajority of the companies have capital spending between 660 and 5,623 thousand dollars. D. E. There is more variation in the fourth quarter than in any of the other quarters. A financial magazine discussed the capital spending of telecommunications companies in the United States and Canada. The capital spendingI in thousands of dollars, for each of a sample of 23 telecommunications companies is provided.

You are also told that you got 381. Did you do well on the exam? Explain your answer. Determine the zscore and interpret this score. states that approximately 99.7% of the observations lie Ascore of 331 has a zscore of . This is standard deviations the mean for this exam. The the mean, this is a score. within Y standard deviations of the mean. Since this score is Y standard deviations (Round to two decimal places as needed.)
