0.45 x 60 = 27
35% x 60 = 21

27-21 = 6 more students prefer math

However, a further 12 students didn't specify whether they prefer maths or science, so you could argue that the answer is 6 +/- 12

Suppose a population has a mean of 7 for some characteristic of interest and a standard deviation of 9.6. A sample is drawn from
valkas [14]

Answer:  A. 1.2

Step-by-step explanation:

Given : Sample size : n= 64

Standard deviation: \sigma=9.6

The formula to find the standard error of mean is given by :-

S.E.=\dfrac{\sigma}{\sqrt{n}}\\\\\Rightarrow\ S.E.=\dfrac{9.6}{\sqrt{64}}\\\\\Rightarrow\ S.E.=\dfrac{9.6}{8}=1.2

Therefore, the standard error of the​ mean= 1.2

Hence, A is the right option.
