Use the data set below to answer the following question. This is a fictitious data set, so no units are listed. Data Set 282 294 270 276 232 295 For the data set above, the Q-test suspect value is type your answer. and based on the statistics you can choose your answer. that value with 90% confidence.

The weight of a metal sphere was measured to be 9.81 g. Unfortunately, the caliper that was supposed to be used in measuring the dimensions of the sphere broke. The metal that make up the sphere was identified to be an alloy of iron and chromium with a density of 7.26 g/cm3. Using the data given, calculate the radius of the metal sphere in cm. Round your answer to 2 decimal places.

4. Calculate the error and percent error of a sample of water using the following data: the actual density of water at 23 °C is 0.999765 g mL-1 and the experimental density (at 23 °C) is 1.097 g mL-1. Show your work and watch your significant figures. O, Focus a

2. For this question you'll need to perform calculations for the data listed below. Imagine you performed the same set of measurements as the instructor did in the video using a 10-mL graduated cylinder. Be sure to show your calculations on this sheet. density of water 0.995124 g/ml mass of empty flask mass of flask + water 24.3165 g, 34.3175 g. 44.1982 g. 54.1597 g. 64.1712 g. 74.2704 g. 84.2420 g. 94.6730 g. 103.9727 g. 114.7728 g 15.5552 g (10 runs) a. Calculate the mean volume of water for the graduated cylinder data above. b. Calculate the standard deviation for the volume of water for the graduated cylinder data typed up above on this page. c. Calculate the standard error for the volume of water for the graduated cylinder data typed up above on this page.
