Answer:
Step-by-step explanation:
Information given
n=370 represent the sample selected
estimated proportion of readers owned a laptop
is the value that we want to test
z would represent the statistic
represent the p value
Creating the hypothesis
We need to conduct a hypothesis in order to test if the true proportion of readers owned a laptop is different from 0.45, the system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
The statistic is:
(1)
Replacing we got:
Calculating the p value
We have a bilateral test so then the p value would be:
Answer:
The answer is 3y= 4x +5
Step-by-step explanation:
Answer:
72 : 18
Step-by-step explanation:
The ratio of the two complementary angles is 4 : 1
4x + 1x = 90
5x = 90
x =18
4x = 4(18) = 72
x = 18
Therefore the ratio is 72 : 18
Answer: 72 : 18
