There are 250 sixth grade students at the school.
Step-by-step explanation:
Given,
Percent of sixth graders who like hip hop = 40%
Number of sixth graders who like hip hop = 100
Let,
x represent the total number of sixth graders at school.
Therefore;
40% of x = 100
Dividing both sides by 0.40

Using the t-distribution, it is found that:
a. The <u>margin of error</u> is of 4.7 homes.
b. The 98% confidence interval for the population mean is (19.3, 28.7).
The information given in the text is:
- Sample mean of .
- Sample standard deviation of .
- Sample size of .
We are given the <u>standard deviation for the sample</u>, which is why the t-distribution is used to solve this question.
The confidence interval is:
The margin of error is:
Item a:
The critical value, using a t-distribution calculator, for a two-tailed <u>98% confidence interval</u>, with 23 - 1 = <u>22 df</u>, is t = 2.508.
Then, the <em>margin of error</em> is:
Item b:
The interval is:
The 98% confidence interval for the population mean is (19.3, 28.7).
