Answer:

the mean and the standard deviation is 0.92 and 0.01808 respectively

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

The mean is 0.92

And, the standard deviation is

= √0.92 × (1 - 0.92) ÷ √225

= √0.92 × 0.08 ÷ √225

= √0.0736 ÷ √225

= √3.27

= 0.01808

Hence, the mean and the standard deviation is 0.92 and 0.01808 respectively

⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)

⇒ (7 x 10⁻¹³) − (0.042 x 10⁻¹³)

⇒ 6.958 x 10⁻¹³

The value of the expression (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵) will be 6.958 x 10⁻¹³. Then the correct option is C.
