A group of statistics students decided to conduct a survey at their university to estimate the average (mean) amount of time stu

shusha [124]

Answer:

C. [21.80, 22.80]

Step-by-step explanation:

We have that to find our $\alpha$ level, that is the subtraction of 1 by the confidence interval divided by 2. So:

$\alpha = \frac{1-0.95}{2} = 0.025$

Now, we have to find z in the Ztable as such z has a pvalue of $1-\alpha$ .

So it is z with a pvalue of $1-0.025 = 0.975$ , so $z = 1.96$

Now, find M as such

$M = z*\frac{\sigma}{\sqrt{n}}$

In which $\sigma$ is the standard deviation of the population and n is the size of the sample.

$M = 1.96\frac{6}{\sqrt{554}} = 0.5$

The lower end of the interval is the sample mean subtracted by M. So it is 22.3 - 0.5 = 21.8 hours.

The upper end of the interval is the sample mean added to M. So it is 22.3 + 0.5 = 22.8 hours

So the correct answer is:

C. [21.80, 22.80]
