We wish to construct a 90% confidence interval on the mean of a population known to be normally distributed based on a sample of

sergiy2304 [10]

Answer:

Margin of error = 0.773

Step-by-step explanation:

We are given the following information in the question.

Sample size, n = 20

Sample mean = 8

Sample standard deviation = 2

90% Confidence interval

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 19 and}~\alpha_{0.10} = \pm 1.729$

Margin of error:

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

Putting the values, we get,

$1.729(\frac{2}{\sqrt{20}} ) = 0.773$

18 is ( blank ) % of 30

meriva

Make an equation.

'is' is an equal sign

The blank can be 'x'

'of' = multiplication

18 = x * 30

Multiply:

18 = 30x

Divide 30 to both sides:

x = 0.6

Multiply by 100:

0.6 * 100 = 60%
