The following graph is an ogive of a standardized test's scores. The vertical axis in an ogive is the cumulative relative frequency and can also be interpreted as a percentile. Complete parts a through c. Find and interpret the percentile rank of a test score with a value of 130. A test score of 130 corresponds to the enter your response hereth percentile rank since this percentage of test scores are greater than or equal to greater than less than or equal to less than a test score with a value of 130.
What is the difference between relative frequency and cumulative frequency? Choose the correct answer below. A. Relative frequency of a class is the number of observations in that class, while cumulative frequency of a class is the sum of all the frequencies. B. Relative frequency of a class is the proportion of the data in that class, while cumulative frequency of a class is the number of observations in that class. C. Relative frequency of a class is the percentage of the data that falls in that class, while cumulative frequency of a class is the sum of the frequencies of that class and all previous classes. O D. There is no difference between the two.

Government agencies keep data about the income distribution of the population. The Watson family and Baker family live in a county with 9000 families. The Watson family's Income is at the 93rd percentile. The Baker family's income is at the 44th percentile. (a) Which of the following must be true about the Watson family's Income? About 93% of the families in their county earn less than the Watson family. O The Watson family earns about 93% of the highest income in their county. O The Watson family's income is in the bottom half of incomes in their county. O The Watson family earns $93,000.

Construct one table that includes relative frequencies based on the frequency distributions shown below, then compare the amounts of tar in nonfiltered and filtered cigarettes. Do the cigarette filters appear to be effective? (Hint: The filters reduce the amount of tar ingested by the smoker.) Click the icon to view the frequency distributions. Complete the relative frequency table below. Relative Relative Tar (mg) (Nonfiltered) (Filtered) 6-9 % % 10-13 % % if 14-17 % % 18-21 % % 22-25 % % 26-29 1% % % % Frequency Frequency 30-33 (Simplify your answers.) Do cigarette filters appear to be effective? O A. Yes, because the relative frequency of the higher tar classes is greater for nonfiltered cigarettes. O B. No, because the relative frequencies for each are not substantially different. O C. No, because the relative frequency of the higher tar classes is greater for filtered cigarettes. O D. This cannot be determined. Frequency Distributions Tar (mg) in Nonfiltered Cigarettes Frequency…

IQ tests supposedly measure our intelligence. They typically are ‘normed’ so that they have a mean of 100 and a standard deviation of 15. (Higher scores show higher intelligence.) Use the graph and use the z-score and percents from columns b and c in Table A, when relevant. If you scored 132, what is your z-score? (Interpret.) Use table A X, z(a), (b), and (c) X z (a) (b) (c) and use the graph! Write down or save your response to use in Part 2 of this quiz. Group of answer choices -2.53 z.
