Mean, median and mode Mean deviation and standard deviation Comment on the precision and accuracy of his readings 2. Define the following terms and give their mathematical representations where necessary: (a) Mean (b) Mean deviation (c) mode (d) Standard deviation 1 (a) Define the terms determinate errors and indeterminate errors and state three differences between the two. (h) Give two types of each of the errors listed above. 4. An analyst analyzed a water sample using a biochemical oxygen demand method and obtained the following results (mg/ml.), 2.43, 3.25, 6.43, 8.23, 3.67, 4.55, 5.93, 4.29, 5.17, and 5.55. The actual value is 4.95 mg/ml From his values, find ta) The mean (b) mean deviation (c) standard deviation (d) from the values, comment on the analyst's precision and accuracy (e) what type of error can be associated to his values 5. if a refrigerator's thermometer is read ten times and registers the temperature in degree Celsius as: 39.1, 39.4, 39.1, 39.2, 39.1, 39.2, 39.1. 39,1. 39.4, and 39.1, whercas the actual temperature inside the refrigerator is 37 degrees C, Find the (a) Mean, median and mode (b) mean and standard deviations (c) comment on the accuracy and precision of the values 6. Calculate the volume (in m' and dm') of 486.6g water at 300K. (density- 0.997g/ml.) 2. A sprinter runs a total distance of 3 miles in 27.0 mins Calculate the speed in meters per second (1 mile 1.609344km) * A 500 ml. beaker containing 350 ml. of benzene weighs 473g. calculate the mass of the beaker given that the density of benzene is 0.878g/ml. OA student purchased solid juice extract from a supermarket and dissolved an unknown amount in water to give a 25% juice solution by weight. If the density of the solution is 1.065g/ml., how many grams of the juice extract are in 100ml of the solution 1O. The following measurements were performed to determine the volume of a given flask at 25°C. (i) Empty flask weighed 48.337g (ii) Flask filled with water weighed = 94.255g (iii) Density of water = 0.99703g/mL Using this data, determine the volume of the flask
