Based on the learned about the variation in the data, which data do you think has more variation: the income of a simple random sample of 500 adults drawn from the general population or the income of a simple random sample of 500 statistics professors? Because?. Question #2. A nutritionist obtains the amounts of sugar (grams) for 10 different cereals, including Cheerios, Corn flakes, Froot Loops, and others. The amounts appear below 3, 24, 30, 47, 43, 7, 47, 13, 44, 39. Calculate the standard deviation of the amount of sugar in the cereal consumed by the population of all Puerto Ricans who eat cereal (Triola, 2004). Question #3 The monthly salary of five (5) employees of a pharmaceutical company was the following for each one: $3,567, $4,235, $3,876, $4,100, and $3278. What should be the value of the standard deviation for these data? Question #4 The waiting times of eight (8) patients to be seen in a medical office, expressed in minutes, were the following: 34, 56, 48, 29, 33, 44, 51, 65. Calculate the following range, variance, and deviation standard. Question #5 The ages of the 10 best actresses in Hollywood are as follows: 32, 48, 51, 63, 57, 60, 52, 54, 48, 71. Use the 10 ages of the best actresses to calculate the interquartile range. Question #6 Use the following sample data to calculate the coefficient of variation for each sample: then compare the results. NUC University male and female student weight: 132, 185, 167, 220, 155, 141, 150. Infant size in inches at birth: 12, 15, 3, 11, 10, 16, 135, 14.8. Question#7 The frequency distribution presented describes the speed at which young people drove to get to take his classes at the University. These young people were driving on a road whose speed limit was 35 mi/h. Calculate the variance and standard deviation. Speed 42-45, 46-49, 50-53, 54-57, 58-61. Frequency 25, 16, 8, 4, 2. Question #8 The following sample data are presented: 1.8, 1.9, 1.8, 2.4, 5.1, 3.1, 5.5, 5.1, 8.3, 13.7, 5.3, 4.9, 3.7, 3.8, 9.8. Calculate the following: a) mean, b) mode, c) median, d) median axis, e) range, f) variance, and standard deviation.
