Answer:
Step-by-step explanation:
Data given and notation
n=1500 represent the random sample taken
estimated proportion of of chips fail in the first 100 hours
is the value that we want to test
represent the significance level
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the actual percentage that fail is different from the stated percentage. Find the value of the test statistic.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statisitc, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion
is significantly different from a hypothesized value
.
Calculate the statistic
Since we have all the info requires we can replace in formula (1) like this:
1. yes
2.no
3.yes
4. no
5. yes
Answer:
Yes.
Step-by-step explanation:
You can use the Pythagorean theorem to figure this out.
5²+12²=13²
25+144=169
169=169
You can also look at the bottom left corner, which is a right angle. All triangles containing right angles are right triangles.
You can also base your answer off of the fact that triangles are kind of like <u>G</u>oogle: They're always right. (jk no that's not true neither are always right)
