Divide the numbers like you would divide two positive numbers using a calculator or long division. Then, when you divide two numbers, and one is positive, and one is negative, the result is negative.

19/13 = 1.46153846...

-19/13 = -1.46153846...

When you divide a negative and a positive, you don't have to worry about the negative that much. Just divide like normal, and then add the negative at the end. However, if you divide a negative by a negative, it's double negative, and therefore positive. So in the case of -19 / 13, the answer would be negative.

Hope this helps! :)

If the inspection division of a county weights and measures department wants to estimate the mean amount of

Amanda [17]

If inspection department wants to estimate the mean amount with 95% confidence level with standard deviation 0.05 then it needed a sample size of 97.

Given 95% confidence level, standard deviation=0.05.

We know that margin of error is the range of values below and above the sample statistic in a confidence interval.

We assume that the values follow normal distribution. Normal distribution is a probability that is symmetric about the mean showing the data near the mean are more frequent in occurence than data far from mean.

We know that margin of error for a confidence interval is given by:

Me= $z/2* ST/\sqrt{N}$

α=1-0.95=0.05

α/2=0.025

z with α/2=1.96 (using normal distribution table)

Solving for n using formula of margin of error.

$n=(z/2ST/Me)^{2}$

n= $(1.96*0.05)^{2} /(0.01)^{2}$

=96.4

By rounding off we will get 97.

Hence the sample size required will be 97.
