As all curved are bell shaped or normal distribution curve, the central position in these curves shows us the mean of the distribution.
Part A : Smallest random error means the curve will have more precision or we can say that the curve with minimum deviation from its mean position. And this is clear from the graphs that the curve 1 has minimum deviation from its mean position.
Hence, the smallest random error curve number is 1.
Part B : From the given plot, it is clear that
the curve 1 and 2 has mean nearly equals to zero.
And the curve 3 has mean somewhere between 0 and 1 .
Hence, the largest mean value curve number is 3 .
For any doubt please comment and please give an up vote. Thank you.

Homework 3 t Gas Density and Molar Mass 6 of 14 > ReviewI Constants Periodic Table ▼ Part B Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since To identify a diatomic gas (X2), a researcher carried out the following experiment: She weighed an empty 4.5-L bulb, then filled it with the gas at 1.30 atm and 24.0 °C and weighed it again. The difference in...
Volume and Moles 6 of 15 > Review Constants Periodic Table Avogadro's law states that the volume, V. of a gas is directly related to the number of moles of the gas when temperature and pressure are constant (Figure 1) Part B Vi Figure A sample of gas in a cylinder as in the example in Part A has an initial volume of 560 L and you have determined that it contains 1.50 moles of gas. The next day you...
ReviewI Constants Periodic Table The air that surrounds us is mostly empty space, and it can be almost a factor of one thousand less dense than water. Within that mostly empty space, gas molecules are moving around at high speed and colliding with each other, and if you are in an enclosed space, they are also colliding with the walls. We can more easily observe the behavior of a gas by confining it to a container with a known volume,...
SET THREE: Chapter 6, Section 1-HT, Exercise 046 Use the normal distribution and the given sample results to complete the test of the given hypotheses. Assume the results come from a random sample and use a 5% significance level. Test H0 : p=0.5 vs Ha : p>0.5 using the sample results p^=0.60 with n=25 Round your answer for the test statistic to two decimal places, and your answer for the p-value to three decimal places. test statistic = ________________ p-value...
Item 26 Review l Constants i Periodic Table Learning Goal: To use partial pressure in gas law calculations In a mixture of gases, the total pressure of the gas mixture is equal to the sum of the partial pressures of the individual gases. For example, if you have a mixture of helium at 2 atm and argon at 4 atm, then the total pressure of the gas inside the cylinder is 6 atm . (Figure 1) Similarly, if you know...

E. Questions Consider the cylinder case. The uncertainty in any one measurement of the density can be determined in the following way. (a) Take the instrumental limit of error associated with the Vernier calipers used to be one-half the least count or smallest measureable increment 8lVernier = 0.001 cm Assume the uncertainty in all linear measurements to be the same and...
I need help filling out the “Q-Test Determination” as well as
the “Post-Lab Questions”
The directions are in the first three pictures, and the
questions I need answered are in the last two pictures.
Thanks.
