Assertion: Mode of the given data 110, 120, 130, 120, 110, 140, 130, 120, 140, 120, is 120.
Reason: The observation that occurs most frequently, i.e., the observation with maximum frequency is called mode.
Which of the following is correct ?

Q. Assertion : If the median of the given data 26, 29, 42, 53, x, x + 2, 70, 75, 82, 93, is 65 then the value of x is 64.
Reason : When the number of observations(n) is odd the median is the value of the ${\left(\frac{n+1}{2}\right)}^{th}$ observation.
Which of the following is correct.

Q.

Assertion: All the points (1, 0), (-1, 0), (2, 0) and (5, 0) lie on the x – axis.
Reason: Equation of the x-axis is y = 0

Choose the correct option.

Q. Assertion :Sulphuric acid is more viscous than water. Reason: Concentrated sulphuric acid has a great affinity for water.

Q. Assertion: The compressibility factor for $H_2$​ and $He$ is $(1+\frac{Pb}{RT})$
Reason: The compressibility factor for $H_2$​ and $He$ can be derived from Van der Waal's equation.

Q. Assertion : Two electrons of helium atom are placed in only one shell but three electrons of lithium need two shells.
Reason: A shell can have maximum ${\text{2n}}^2$ electrons.
