Hey, can anyone help me? My math question is: "What sort of information can you get from conditional frequencies that you couldn

Answer:
Null Hypothesis:
Alternative hypothesis: (Changes on the deviation)
Step-by-step explanation:
s represent the sample standard deviation
represent the population standard deviation (variable of interest)
represent the value that we want to test
n represent the sample size
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
Based on this the system of hypothesis should be:
Null Hypothesis:
Alternative hypothesis: (Changes on the deviation)
In order to test these system of hypothesis we need to select a significance level , then we need to calculate an statistic given by this formula.
Then we need to calculate the degrees of freedom for the statistic on this case
And after this we need to calculate the pvalue based on the significance, the alternative hypothesis and the statistic calculated.
If the we reject the null hypothesis
If the we FAIL reject the null hypothesis
Hey there! :D
When you are finding the area of corresponding sides, you square the number of the ratio of the similar lengths.
The screens a little blurry, but I'm assuming the corresponding side is represented as:
So, you would keep a and b where they are, (you would be confusing the areas if you switched it in any way) and then just square the variables.
"C" is the best answer.
I hope this helps!
