Construct the cumulative frequency distribution for the given data. Age (years) of Best Actress when award was won Age (years) of Best Actress when award was Cumulative Frequency Frequency won 20-29 28 Less than 30 30-39 33 40-49 11 Less than 40 50-59 Less than 50 60-69 70-79 Less than 60 80-89 Less than 70 Less than 80 " . . Less than 90Find the (a) mean, (b) median, (c) mode, and (d) midrange for the given sample data. An experiment was conducted to determine whether a deciency of carbon dioxide in the soil affects the phenotype of peas. Listed below are the phenotype codes where 1 =smoothryellow, 2 = smoothgreen, 3 = wrinkledryellow, and 4 =wrinkledgreen. Do the results make sense? 2 2 3 3 3 4 3 1 3 3 1 2 2 1 |E (a)The mean phenotype code is |_|. (Round to the nearest tenth as needed.) (b)The median phenotype code is (Type an integer or a decimal.) (c) Select the correct choice below and ll in any answer boxes within your choice. O A- The mode phenotype code is . (Use a comma to separate answers as needed.) 0 B. There is no mode. (d)The midrange of the phenotype codes is (Type an integer or a decimal.) Do the measures of center make sense? 0 A. Only the mean, median, and midrange make sense since the data is nominal. O B. Only the mean, median, and mode make sense since the data is numerical. O C. All the measures of center make sense since the data is numerical. Determine whether the followmg procedure results in a binomial distribution or a distribution that can be treated as binomial (by applying the 5% guideline for cumbersome calculations}. If it is not binomial and cannot be treated as binomial. identify at least one requirement that is not satised. In a Pew Research Center sunreiir of 50 subjects, the ages of the respondents are recorded. Choose the correct answer below. O A. It is binomial or can be treated as binomial. O B. It is not binomial because the probability of success does not remain the same in all trials. C. It is not binomial because there are more than two possible outcomes and the trials are not independent. O D. It is not binomial because there are more than two possible outcomes. Find the area of the shaded region. The graph to the n'ghtdepicts IQ scores of adults, and those scores are normally distributed with a mean of 100 and a standard deviation of 15. 106 132 '09 The area of the shaded region is _ (Round to four decimal places as needed.)
