In order to redraw a scale drawing with a new scale, here are the steps that you need to follow : 1. Measure up the current scale and the size of the drawing 2. Determine the ratio of the second scale 3. Adjust the size and dimension of the first drawing into the new scale based on the previously calculated proportion

An agronomist wishes to estimate, to within one percentage point, the proportion of a new variety of seed that will germinate wh

Galina-37 [17]

Answer:

The minimum sample size must be 1118 to have margin of error within one percentage point.

Step-by-step explanation:

We are given the following in the question:

Germination rate = 97% = 0.97

$\hat{p} = 0.97$

Margin of error = 1% = 0.01

We have to find the minimum sample size for a 95% confidence interval.

Formula for margin of error:

$z_{stat}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = 1.96$

Putting values, we get,

$1.96\times \sqrt{\dfrac{0.97(1-0.97)}{n}}\leq 0.01\\\\\sqrt{n} \geq 1.96\times \dfrac{\sqrt{0.97(1-0.97)}}{0.01}\\\\\sqrt{n}\geq 33.4350\\\Rightarrow n \geq 1117.9056$
