The correct answer for this question is this one: "
Calculation:
<span>50*.64 + 85*.4= 66</span>
The statement shown above is a topic under Statistics and Probability. As it was said that
<span>The conditional relative frequency table was generated using data that compares the number of voters in the last election and whether or not they worked on election day. Fifty people who voted and 85 people who did not vote were chosen at random and surveyed.
</span>
There exists the same question from other source:
How many people in the survey worked on election day?
32
34
66
69
Hope this helps answer your question and have a nice day ahead.
Answer:
58.25
Step-by-step explanation:
58 1/4 in decimal form = 58.25
For this problem your equation will be x+(x+1)+(x+2)=537
Multiply and Simplify:
x+x+1+x+2=537
3x+3=537
Subtract 3 from both sides:
3x+3-3=537-3
3x=534
Divide both sides by 3:
3x/3=537/3
x=179
179 is the middle number so: 178+179+180=537
180 is the third number.
Using the confidence interval, it is found that the correct conclusion regarding the hypotheses test is given by:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
<h3>What are the hypotheses tested?</h3>
At the null hypotheses, it is tested if the mean is of 150, that is:

At the alternative hypotheses, it is tested if the mean is different of 150, hence:
.
The confidence interval is (158, 167). Since it does not contain 150, we reject the null hypotheses, hence the correct option is:
Reject H0. There is convincing evidence that this individual’s true mean heart rate while working out differs from 150.
