Awnser:
You can fit up to 64 cubes in the rectangular prism.
Step-by-step explanation:
Well, we know that each side measures 4 inch each.
So, 4(L) x 4(W) x 4(H) = 64.
100% - 7% - 30% = 63% of people are on the sand
Answer:
Given :An Internet survey was e-mailed to 6977 subjects randomly selected from an online group involved with ears. There were 1337 surveys returned.
To Find : Use a 0.01 significance level to test the claim that the return rate is less than 20%.
Solution:
n = 6977
x = 1337
We will use one sample proportion test



We are given that the claim is the return rate is less than 20%.

Formula of test statistic = 
= 
= 
Refer the z table
P(z<-1.85)=0.0332
Significance level = 0.01=α
Since p value > α
So, we accept the null hypothesis .
So,the claim that the return rate is less than 20% is false.
