Answer:
Step-by-step explanation:
Given that
sample size n = 55: x bar = 654.16 and s = sample sd = 162.34
Std error = 162.34/sqrt 55 = 21.889
For 95% CI we can use t critical value as population std dev is not known.
df = 54
t critical = 2.004
Margin of error = 2.004 *21.889 = 43.866
Confidence interval lower bound = 654.16-43.866 =610.294
Upper bound = 654.16+43.866=698.026
Confidence interval rounded off at 95% = (610.29, 698.23)
Answer:
45.34
Step-by-step explanation:
you have to use the pythagorean theorem
The answer is B. The last too are both negative. So they are not true numbers.
6 marbles per person.
If we count the number of marbles in total, we get 24: 5+9+4+6= 24
Now that we know the Total # of marbles, we need to know how many people we need to distribute marbles to. We count Brian, Sarah, Jimi, and Juan and get 4 people in total.
To find how many marbles each person needs to receive, we then need to do 24 divided by 4.
When we do this, we get 6 marbles per person.
Idk sorry try making a question next time
