Answer:
D. 6
Step-by-step explanation:
Here we are given that a sample of 256 was taken from a population with a standard deviation of 96 centimeters i.e.
= 96 and n = 256.
And we have to calculate the margin of error for a 68% confidence interval.
Firstly from z score% table we observe that at 32% level of significance the z score critical value is given by 0.99744 .
<em>And Margin of error formula is given by ;</em>
*
= 0.99744 *
= 5.98
Approximately, we get Margin of error = 6.
Answer:
259.99
Step-by-step explanation:
You look at the hundreths place and see if the number behind it is bigger than 5, and if it is then you up it by one, and if it's 4 and below then you round it to zero. In this case you up it by one and you get 269.99.
I hope this helps!!!!
