The top row contains the product of
with each term of the expressions
and bottom row contains the product of -1 with each term of expression
.
The final result will be the sum of terms of both rows as shown below:
So the correct answer is option D
Answer: 10,956
Step-by-step explanation: A
Answer:
204,160,000
Step-by-step explanation:
Assuming the sample is a good representation of the people from the United States.
Since there were 1,000 surveyed... and 638 of them were wearing glasses, that makes a proportion of 638 out of 1,000 people, or 63,8 / 100 people... so 63.8%... or 0.638
So, if we assume that the US population is of 320 million, how many people does that make wearing glasses.... we just have to multiply 320M by 0.638
G = 320,000,000 * 0.638 = 204,160,000
Alpha level. the minimum P-value at which we reject the null hypothesis
<h3>What is Null hypothesis ?</h3>
That two options are identical is the null hypothesis. According to the null hypothesis, the observed difference is solely the result of chance. The probability that the null hypothesis is correct can be determined via statistical testing.
<h3>What is alpha level?</h3>
The "significance level," often known as the alpha level, must be established before performing any statistical test. The likelihood of rejecting the null hypothesis when it is true is what is meant by the term "alpha level" in statistics. The likelihood of making a poor decision is what this phrase means.
