ICE Princess25 [194]

Answer:

Option C) 5.62 points

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 20

Sample mean score = 64

Sample standard deviation, s = 12

Degree of freedom =

$=n-1\\=20-1\\=19$

We have to calculate margin of error for a 95% confidence interval.

Formula for margin of error:

$t_{critical}\times \displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 19 and}~\alpha_{0.05} = \pm 2.093$

$2.093\times (\displaystyle\frac{12}{\sqrt{20}} )\\\\ =5.6161\approx 5.62$

Thus, the correct answer is

Option C) 5.62 points
