Answer:
1 3/8
Step-by-step explanation:
Well to find the average or the mean we need to add all the numbers,
3/8 + 2/4 + 5/8 + 7/8 + 1 1/8 + 1 5/8 + 1 7/8 + 4
= 11
Then we divide t by the number of numbers in the set.
11 ÷ 8 = 1 3/8
<em>Thus,</em>
<em>the average in the set is 1 3/8.</em>

Answer:
An interval that will likely include the proportion of students in the population of twelfth-graders who carry more than $15 is 960
Step-by-step explanation:
For example, Condition 1: n(.05)≤N
• The sample size (10) is less than 5% of the population (millions of musicians), so
the condition is met.
• Condition 2: np(1-p)≥10
• =
2
10
= .2
• 1 − = 10 .2 1 − .2 = 1.6 . This is less than 10 so this condition is not
met.
It would not be practical to construct the confidence interval.
