2^30=1073741824

scientific notation is (number that is greater than or equal to 1 but less than 10) times 10^n

so
1073741824=
107374182.4 times 10¹=
10737418.24 times 10²=
etc
1.073741824 times 10⁹ is scientific nottaion

Galina-37 [17]

Answer:

The minimum sample size required for the estimate is 345.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1 - 0.95}{2} = 0.025

Now, we have to find z in the Ztable as such z has a pvalue of 1 - \alpha.

That is z with a pvalue of 1 - 0.025 = 0.975, so Z = 1.96.

Now, find the margin of error M as such

M = z\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

The standard deviation is known to be 1.8.

This means that \sigma = 1.8

What is the minimum sample size required for the estimate?

This is n for which M = 0.19. So

M = z\frac{\sigma}{\sqrt{n}}

0.19 = 1.96\frac{1.8}{\sqrt{n}}

0.19\sqrt{n} = 1.96*1.8

\sqrt{n} = \frac{1.96*1.8}{0.19}

(\sqrt{n})^2 = (\frac{1.96*1.8}{0.19})^2

n = 344.8

Rounding up to the next integer:

The minimum sample size required for the estimate is 345.
