Four students in an art class mixed red and blue paint to make purple. The amounts they used are shown in the table. Which stude
1 answer:
Based on the mixtures of the four students in the art class, the student with a different shade of purple would be Aiden.
<h3>Why would Aiden's mixture be different?</h3>In order to solve this question, look at the ratio of red paint to blue paint for all the students:
Alec:
1¹/₃ : ²/₃
2 : 1
Rosa:
2¹/₂ : 1 ¹/ ₄
2 : 1
Aidan:
4¹/₂ : 2
2.25 : 2
Zoe:
5 : 2¹/₂
2 : 1
Notice that Aidan's mixture is the only one that is different and so will have a different shade of purple as a result.

Answer:
The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
92% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).
