Answer #1

a) Because it is a liquid, the best technique is to measure approximately 5 g of gasoline and weigh this sample, the density is calculated: d = mass / volume.

b) Weigh 5 g of sugar and measure its volume.

c) The lump is weighed, a certain volume of water is measured, the lump is introduced into the water and the new volume is measured, the lump volume is obtained by difference.

d) Volume and mass are measured as a fluid substance, density is calculated.

If you liked the answer, please rate it positively, you would help me a lot, thanks.

A hospital administrator wants to determine the proportion of emergency room patients that use the emergency room (ER) for non-emergency care. She randomly samples records from 350 ER patients and determines that 74 of those patients required only non-emergency care. 1. The administrator constructs a 90% confidence interval for the true proportion of all ER patients who use the ER for non-emergency care. The error bound for the proportion EBP for this confidence interval is: A. 0.036 B. 0.072 C....
