The manager at Green Tee's golf course conducted a study to see how long it takes to complete a round of golf. The manager records the
time it takes randomly selected golfers to finish a round of golf at Green Tee's golf course. The manager conducts the survey on a golf league
day, therefore all the golfers within the sample have previous golf experience. Based on the study, the average time spent to complete a
round of golf was 4 hours.
What inference can be made from the survey?
O A On average, it will take 4 hours to complete a round of golf.
OB. On average, it will take 4 hours to complete a round of golf at Green Tee's golf course,
O c. On average, it will take a golfer with previous experience 4 hours to complete a round of golf,
OD. On average, it will take a golfer with previous experience 4 hours to complete a round of golf at Green Tee's golf course,

Farmers know that driving heavy equipment on wet soil compresses the soil and injures future crops. here are data on the "penetrability" of the same type of soil at two levels of compression. penetrability is a measure of how much resistance plant roots will meet when they try to grow through the soil. compressed soil 2.85 2.66 3 2.82 2.76 2.81 2.78 3.08 2.94 2.86 3.08 2.82 2.78 2.98 3.00 2.78 2.96 2.90 3.18 3.16 intermediate soil 3.17 3.37 3.1 3.40 3.38 3.14 3.18 3.26 2.96 3.02 3.54 3.36 3.18 3.12 3.86 2.92 3.46 3.44 3.62 4.26 use the data, omitting the high outlier, to give a 95% confidence interval for the decrease in penetrability of compressed soil relative to intermediate soil. compute degrees of freedom using the conservative method. interval: to

An oil exploration company currently has two active projects, one in asia and the other in europe. let a be the event that the asian project is successful and b be the event that the european project is successful. suppose that a and b are independent events with p(a) = 0.2 and p(b) = 0.8. (a) if the asian project is not successful, what is the probability that the european project is also not successful? (b) what is the probability that at least one of the two projects will be successful? (c) given that at least one of the two projects is successful, what is the probability that only the asian project is successful? (round your answer to three decimal places.)
