Suppose a sample of 256 was taken from a population with a standard deviation of 96 centimeters. What is the margin of error for
astraxan [27]

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. \sigma = 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>

                        Z_\frac{\alpha}{2} * \frac{\sigma}{\sqrt{n} } = 0.99744 * \frac{96}{\sqrt{256} } = 5.98

Approximately, we get Margin of error = 6.

Please can someone help me solve 10x+5=15
telo118 [61]

Answer: The value of x is 1

Step-by-step explanation:

10x + 5 = 15

Collect the like terms which in this case are the whole numbers "5" and "15")

10x = 15 - 5

10x = 10

Divide both sides by 10

10x/10 = 10/10

x = 1

Thus, the value of x is 1
