MATH 1280 Self - Quiz Unit 2– University of the People Information text The next two questions refer to the following relative frequency table on hurricanes that have made direct hits on the U.S. between 1851 and 2004. Hurricanes are given a strength category rating based on the minimum wind speed generated by the storm. Frequency of Hurricane Direct Hits Category # Direct Hits Relative Freq. Cum. Relative Freq. 1 0.39930 0.3993 2 72 3 0.2601 4 0.0659 5 0.0110 1.0...

MATH 1280 Self-Quiz Unit 7 (100%) – University of the People Grade 10.00 out of 10.00 (100%) Information text Recall that the population average of the heights in the file "" is μ = 170.035. Using simulation it can be shown that the probability of the sample average of the height falling within 2 centimeter of the population average is approximately equal to 0.925. From the simulations we also got that the standard deviation of the sample average is (approximately) equal to 1.122. In the...

MATH 1280 Self-Quiz Unit 3 (100%) – University of the People Grade 10.00 out of 10.00 (100%) Question 1 Correct Question text In Figure A you will find box plots for three sets of data. In Figure B are the histograms for the same sets of data, but in a different order. Associate each box plot with its relative histogram. Figure A: Figure B:

What is the relative frequency of direct hits that were category 2 hurricanes? Select one: a. 0.2637 b. 0.7363 c. 0.2601 d. Not enough information to calculate. The total of all relative frequencies is 1.000. Denote by p the relative frequency of category 2 hurricanes. Observe that 0.3993 + p + 0.2601 + 0.0659 + 0.0110 = 1.0000 Consequently, p = 1 - 0.3993 + 0.2601 + 0.0659 + 0.0110 = 1 - 0.7363 = 0.2637 The correct answer is: 0.2637
