It's a quadratic equation. Solve it through factorisation.

5s^2 - 14s - 3 = 0
(5s + 1)(s - 3) = 0

5s + 1 = 0
or
s - 3 = 0

Therefore

s = -1/5
or
s = 3

Tresset [83]

Answer:

Option C

Step-by-step explanation:

The standard deviation of any sample is inversely proportional to the size of the sample. Thus, as the sample size increases, the standard deviation reduces or vice versa. Thus, option A is in correct

As the sample size increases, the confidence in estimate also increases Hence, option B is also incorrect

Option D is true to its words , hence it is also a wrong choice for this question

Hence, option C is correct
