Hey there! :D

The tenth place is where the first 6 is, so:

1.666666666667=

1.7 because 6>5

To round a number to the tenth, any number greater than or equal to 5 will round up and anything less than 5 round down.
So, the number after the tenths place is a 6 which is greater than 5, so you would round up.
So, your answer would be 1.7

Answer:

$n=\frac{0.5(1-0.5)}{(\frac{0.03}{1.96})^2}=1067.11$

And rounded up we have that n=1068

Step-by-step explanation:

We have the following info given:

$Confidence= 0.95$ the confidence level desired

$ME =0.03$ represent the margin of error desired

The margin of error for the proportion interval is given by this formula:

$ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}$ (a)

The confidence level is 95% or 0.95, the significance is $\alpha=0.05$ and the critical value for this case using the normal standard distribution would be $z_{\alpha/2}=1.96$
