Question 1
Use the relative frequency method to estimate the probability. Round your answer to three decimal places.
A polling firm, hired to estimate the likelihood of the passage of an up-coming referendum, obtained the set of survey responses to make its estimate. The encoding system for the data is:
If the referendum were held today, estimate the probability that it would pass.
1, 2, 2, 1, 1, 2, 1, 2, 2, 1, 1, 1, 2, 1, 2, 1, 1, 1, 2, 1
◦ 0.5
◦ 0.65
◦ 0.6
◦ 0.4
Question 2
Use the relative frequency method to estimate the probability. Round your answer to three decimal places.
The data set represents the income levels of the members of a country club. Estimate the probability that a randomly selected member earns at least $82,000.
92,000 102,000 76,000 107,000 79,000 92,000 82,000 70,000 117,000 142,000
112,000 79,000 102,000 97,000 82,000 122,000 67,000 97,000 73,000 87,000
◦ 0.8
◦ 0.6
◦ 0.4
◦ 0.7
