Can someone help me with this? Please with the steps to get to the result, so I understand it better. Thank you

present the processes necessary to support the answers to the exercises and round the final results ? not the intermediate values ??that appear during the calculations ? to two decimal places, when necessary.

Question # 1

1) A nutritionist obtains the amounts of sugar (grams) from 10 different cereals, including Cheerios, Corn Flakes, Froot Loops, and seven others. The amounts are shown below: 6, 24, 33, 47, 43, 7, 41, 23, 44, 39. Calculate the standard deviation of the amount of cereal sugar consumed by the population of all Puerto Ricans who eat cereal (Triola , 2004).

Question # 2

1) The monthly salary of five (5) employees of a pharmaceutical company was as follows: $ 3,667, $ 4,935, $ ??3,876, $ 4,700 and $ 3,178. What should the value of the standard deviation be for those data? (4 points)

Question # 3

1) The waiting times of eight (8) patients to be seen in a medical office, expressed in minutes, were the following: 34, 46, 42, 29, 31, 34, 51, 63. Calculate the following: range, variance and standard deviation.

Question # 4

1) The ages of the 10 best actresses in Hollywood are: 33, 48, 51, 35, 57, 67, 52, 44, 48, 70. Use the 10 ages of the best actresses to calculate the interquartile range.

Question # 5

1) Use the following sample data to calculate the coefficient of variation for each sample; then compare the results.

Weight of students of both sexes at NUC University: 159, 165, 197, 200, 165, 143, 154

Size in inches of babies at birth: 12.2, 15.3, 11.4, 10, 15.8, 13.5, 14.1

Question # 6

2) The frequency distribution presented describes the speed at which some young people drove to get to take their classes at the university. These young people were driving on a road with a speed limit of 35 mi / h. Find the variance and standard deviation.

Speed Frecuency

Velocidad Frecuencia 42-45 20 46-49 16 50-53 11 54-57 58-61
