Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

The owner of a golf course wants to determine if his golf course is more difficult than the one his friend owns. He has 26 golfers play a round of 18 holes on his golf course and records their scores. Later that week, he has the same 26 golfers play a round of golf on his friend's course and records their scores again. The average difference in the scores (treated as the scores on his course - the scores on his friend's course) is -1.79 strokes and the standard deviation of the differences is 5.907 strokes. The owner uses this information to calculate the 90% confidence paired t-interval of (-3.769, 0.189). Which statement is the correct interpretation of this interval? Question 10 options: 1) We are 90% confident that the difference between the average score on the owner's golf course and the average score on the friend's golf course is between -3.769 and 0.189. 2) We are certain the average difference in scores between the two…

During harvesting season at a coffee plantation in puerto rico, hand pickers collect about 165 lbs. of coffee cherries per day. The coffee harvester machine collects about 18,000 pounds of coffee cherries per day. Only 20 % of the coffee cherry's weight is the actual coffee bean. Let h represent the number of days the hand pickerswork and m represent the number of days the harvester machine is used. Which of the algebraic expressions can be used to estimate the amount of coffee beans collected, in pounds , in the coffee plantation during this harvesting season? A) 0.2 (165h + 18,000m) B) 165h + 0.2 (18,000m) C) 165h + 18,000m/ 20 D) 165.2h + 18,000.2m
