Assoli18 [71]

Question:

You are interested in estimating the the mean age of the citizens living in your community. In order to do this, you plan on constructing a confidence interval; however, you are not sure how many citizens should be included in the sample. If you want your sample estimate to be within 5 years of the actual mean with a confidence level of 97% , how many citizens should be included in your sample? Assume that the standard deviation of the ages of all the citizens in this community is 18 years.

Answer:

61.03

Step-by-step explanation:

Given:

Standard deviation = 18

Sample estimate = 5

Confidence level = 97%

Required:

Find sample size, n.

First find the Z value. Using zscore table

Z-value at a confidence level of 97% = 2.17

To find the sample size, use the formula below:

$n = (Z * \frac{\sigma}{E})^2$

$n = ( 2.17 * \frac{18}{5})^2$

$n = (2.17 * 3.6)^2$

$n = (7.812)^2$

$n = 61.03$

Sample size = 61.03

The answer is B. 34.7

Take the cosine (adjacent over hypotenuse) of 38°
Multiply this number by 44 (the hypotenuse)

Your answer is 34.67, which rounds to 34.7
