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,

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

Rounding off to integer,

$n = 1118$

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

As treasurer of his school's FFA club, Kenny wants to buy gifts for all 18 members. He can buy t-shirts for $9 and sweatshirts f

DanielleElmas [232]

Kenny can buy 15 t shirts and 3 sweatshirts.

Step-by-step explanation:

Given,

Number of members = 18

Cost of each t shirt = $9

Cost of each sweatshirt = $15

Money = $180

Let,

x be the number of t shirts

y be the number of sweatshirts

According to given statement;

x+y=18 Eqn 1

9x+15y=180 Eqn 2

Multiplying Eqn 1 by 9

$9(x+y=18 )\\9x+9y= 162\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(9x+15y)-(9x+9y)=180-162\\9x+15y-9x-9y=18\\6y=18\\$

Dividing both sides by 6

$\frac{6y}{6}=\frac{18}{6}\\y=3$

Putting y=3 in Eqn 1

$x+3=18\\x=18-3\\x=15$

Kenny can buy 15 t shirts and 3 sweatshirts.
