The frequencies were as follows. Complete parts (a) through (g). Relative Response Frequency Response Frequency Never Never 416 Rarely Rarely 326 Sometimes Sometimes 935 Most of the time Most of the time 365 Always Always 95 (Round to three decimal places as needed.)The following table lists length of stay (days) in hospital for a sample of 25patients5,10,6,11,5,14,30,11,17,3,9,3,8,8,5,5,7,4,3,7,9,11,11,9,41(a). Construct a frequency/relative frequency table for these data using 5days class intervals. Include coloums for the frequency counts,relative frequencies and cumulative frequencies.(I)what percentage of hospital stays were less than 5days?(ii)what percentage of hospital stays were less than 15days?(ii)what percentage of hospital stays were at least 15days in length?1b (I) using the above data calculate the mean,median and mode (ii) explain why the mean and madian are different
- Answer don't explain. TYThis exercise involves a complementary event. Find the probability of the given event. Assume that the deck is fair. Not drawing a red card from a standard deck of 52 playing cards The probability of not drawing a red card is (Type an integer or a simplified fraction.)How do I construct a frequency table with grouped data with the following problem? I would also like to know how the frequency scores are calculated from the interval data. Suppose we have collected weights from 100 male subjects as a part of a nutrition study. For our weight data, we have values ranging from a low of 121 pounds to a high of 263 pounds, giving the total span of 263-121=142. Determine reasonable class intervals for a frequency table.
- TYPE I: FREQUENCY DISTRIBUTIONS AND GRAPHICAL TECHNIQUES 8. The National Safety Council reports the following age breakdown for licensed drivers in the India. Identify the following for the 35-under 45 class: Age (Years) Number of Deaths (Thousands) Under 15 40.01 15-under 25 33.08 25-under 35 41.38 35-under 45 91.01 45-under 55 172.21 55-under 65 253.73 65-under 75 424.11 75 or over 1391.99 (a) frequency, (b) upper and lower limits, (c) width, and (d) midpoint.5. The female students in an undergraduate engineering core course at UH self-reported their heights to the nearest inch. The data is as follows. 62 64 61 67 65 68 61 65 60 65 64 63 59 68 64 66 68 69 65 67 62 66 68 67 66 65 69 65 69 65 67 67 65 63 64 67 65 First construct the frequency distribution Table like Table 6-4 on Page 213 of textbook where you only need to specify the classes/bins, frequency info. Then using the table to create the histogram; here let the height of rectangle (for each bin) equal to the frequency instead of relative frequency in your histogram even though you can also set the height as the relative frequency. Hint: create the frequency distribution table by hand, but you can create the histogram in Excel and insert the result as a figure.Resting Pulse: earlier this semester we determined our resting pulse. Seventy-nine individuals participated in this data collection. The mean heart rate for all individuals was 65.34 beats per minute. A random sample of 30 heart rates having a mean of 64.97 beats per minute is presented here. Build a frequency table of these data containing six (6) classes with the lower llimit of the second class at 54 beats per minute. Build a chart appropriate for the presentation of these data. Data: 49, 51, 53, 56, 57, 58, 60 , 60, 62, 62, 62, 64, 64 65, 65 , 65, 67, 68, 68, 68, 69, 70 , 70, 72, 72, 72, 72, 75, 75 , 78,
- A graduate-level computer science course only gives the grades of A, B, or C. The department has determined that there should be 40% A's given, 40% B's given and 20% C's given as final grades for the course. For the spring 2021 semester, 200 students took the course and 100 students received A's, 50 students received B's and 50 students received C's, so those are my observed frequencies. We want to do a Chi-square Multinomial Goodness of Fit test to see if our grading guidelines match up with what is actually happening. What is the expected frequency for the grade of B category? Round your answer to the tenths position.The frequency distribution table below is the net weight of a sample of candied fruit products in the food industry cans "ABC": - How many cans have a net weight of less than 20.2 grams. - If we want to compare about the distribution of net weight with the food company "XYZ" for the same type of product. And it is known that the average and variance is 20 grams and 0.04 grams. Which food company has an even distribution of net weight.Table 3 shows the distribution for the number of medical leaves (in days) taken within a certain period by 65 employees of accompany. Number of medical leaves Number of employees (days) 1-3 4 4 -6 7-9 8 10 - 12 12 13 - 15 18 16 - 18 11 19 - 21 Table 3: The number of medical leaves (in days) (a) Draw a cummulative frequency curve to illustrate the data. (Note : Use graph sheet) (b) Using the ogive in question 4(a), estimate the median and third quartile value. (c) Calculate the mean, and standard deviation from the data given in Table 3.
