The volume of a cone can be found as:
Given the radius and height, we can find the volume of the cone:
The volume of a sphere is:
So, for each gum ball the volume is:
Therefore, the he closest approximation of the volume of the cone that can be filled with flavored ice is:
Conclusion: The volume of the cone that can be filled with flavored ice is 4.43 cubic inches.
Answer:
The value of test statistics is 25.
Step-by-step explanation:
We are given below the SAT reading and writing section scores of a random sample of twenty 11th-grade students in a certain high school;
380, 520, 480, 510, 560, 630, 670, 490, 500, 550, 400, 350, 440, 490, 620, 660, 700, 730, 740, 560
<em>Let </em><em> = population standard of the reading and writing section SAT score of the students in this school</em>
So, Null Hypothesis, :
100 {means that the reading and writing section SAT score of the students in this school is lesser than or equal to 100}
Alternate Hypothesis, :
<em> </em>> 100 {means that the reading and writing section SAT score of the students in this school is higher than 100}
The test statistics that would be used here is <u>One-sample Chi-square</u> test statistics;
T.S. = ~
where, = sample variance =
= 13135.8
n = sample of 11th-grade students = 20
So, <u><em>the test statistics</em></u> =
= 24.96 ≈ 25
Hence, the value of test statistics is 25.
