Answer:

Statistical significance is based on the value of the probability of committing a type I error when executing a hypothesis test under the assumption that the null hypothesis is true. That is, the conditional probability of rejecting the null hypothesis, given that said null hypothesis is true. To the extent that the probability of committing the type I error is smaller, the conclusion obtained from the test will be more significant.

Therefore, statistical significance means that the likelihood of getting these results by chance is very small.

A total of
Airida [17]
A+s=496

s=496-a

and we are also told that:

s=3a

Since s=s we can say:

3a=496-a  add a to both sides

4a=496  divide both sides by 4

a=124

So 124 adult tickets were sold.

When you multiply two integers with the same signs, the result is always positive. Just multiply the absolute values and make the answer positive.</span>

<span>Positive x positive = positive 
Negative x negative = positive</span>

<span>When you multiply two integers with different signs, the result is always negative. Just multiply the absolute values and make the answer negative.</span>
