Height distributions generally have a predictable pattern. In a large introductory statistics class, students were asked to reporttheir height. The histogram displays the distribution of heights, in inches, for 266 females from this class.80-70-60-50-40-30-20-10-55 57 59 61 63 65 67 69 7173 75Height (inches)Describe the shape, center, and variability of this distribution.Number of females

Listed below are pulse rates (beats per minute) from samples of adult males and females. Find the mean and median for each of the two samples and then compare the two sets of results. Does there appear to be a difference? Male: 95 77 64 88 62 72 53 82 56 79 53 53 54 76 55 Female: 65 63 87 89 84 76 87 68 93 88 69 93 82 87 70 Find the means. The mean for males is beats per minute and the mean for females is beats per minute. (Type integers or decimals rounded to one decimal place as needed.) Find the medians. The median for males is beats per minute and the median for females is beats per minute. (Type integers or decimals rounded to one decimal place as needed.) Compare the results. Choose the correct answer below. O A. The mean and the median for males are both lower than the mean and the median for females. O B. The mean and the median for females are both lower than the mean and the median for males. O C. The mean and median appear to be roughly the same for both genders. O D. The…

The figure shows population density (people per square mile) for all states of a certain country. The states are divided into four geographical regions: A, B, C, and D. Answer the questions below. D- 0 100 200 300 400 500 600 700 800 900 1000 1100 People per Square Mile Why is it best to compare medians and interquartile ranges for these data, rather than comparing means and standard deviations? OA. These data are fairly symmetric and do not have outliers, and the median and interquartile range provide more reliable information in these circumstances. B. Some of these data have outliers and/or are skewed, and the median and interquartile range amplify the effects of outliers and skewness. OC. Some of these data have outliers and/or are skewed, and the median and interquartile range are resistant to outliers. OD. Some of these data have vastly different centers, and the median and interquartile range provide more reliable information in these circumstances. List the approximate median…
Question: The data for the manufacturing time (in days) of batteries is collected. The number of batteries that take between 40 and 50 days to be manufactured is not known, this is termed as frequency y. If the mean of the given frequency distribution is 35, then find the missing frequency y. Also, calculate the median and mode for the distribution and infer whether it is symmetrical or asymmetrical distribution 34 21 11 25 38 35 59 34 32 39 36 15
