To reduce laboratory costs, water samples from three public swimming pools are combined for one test for the presence of bacteria. Further testing is done only if the combined sample tests positive. Based on past results, there is a 0.008 probability of finding bacteria in a public swimming area. Find the probability that a combined sample from three public swimming areas will reveal the presence of bacteria. Is the probability low enough so that further testing of the individual samples is rarely necessary? The probability of a positive test result is. (Round to three decimal places as needed.) Is the probability low enough so that further testing of the individual samples is rarely necessary? O A. The probability is quite low, indicating that further testing of the individual samples will be a rarely necessary event. O B. The probability is quite low, indicating that further testing is not necessary for any of the combined samples. O C. The probability is quite high, indicating that further testing of the individual samples will frequently be a necessary event. O D. The probability is quite high, indicating that further testing is necessary for all of the combined samples.

A new framework of data analysis where the new statistical methods are used for interpreting the results and analyzing the data is known as estimation in statistics.

Question

To reduce laboratory costs, water samples from three public swimming pools are combined for one test for the presence of bacteria. Further testing is done only if the
combined sample tests positive. Based on past results, there is a 0.008 probability of finding bacteria in a public swimming area. Find the probability that a combined sample
from three public swimming areas will reveal the presence of bacteria. Is the probability low enough so that further testing of the individual samples is rarely necessary?
The probability of a positive test result is.
(Round to three decimal places as needed.)
Is the probability low enough so that further testing of the individual samples is rarely necessary?
O A. The probability is quite low, indicating that further testing of the individual samples will be a rarely necessary event.
B. The probability is quite low, indicating that further testing is not necessary for any of the combined samples.
O c. The probability is quite high, indicating that further testing of the individual samples will frequently be a necessary event.
O D. The probability is quite high, indicating that further testing is necessary for all of the combined samples.

A study reported that about 40% of high school students have tried out for a sport at their school. To find out if this applies to Jessica’s school, she surveyed an SRS of 20 students. Nine of them said that they had tried out for a sport. To see if this result is surprising, a simulation is to be conducted to estimate the probability of obtaining a sample result as high as this one. Let 0–3 represent students who tried out for a sport and 4–9 represent students who did not try out for a sport. Using the line of random numbers to run one simulation, what proportion of students tried out for a sport? 0.40 0.45 0.50 0.60
