Suppose a sample of 256 was taken from a population with a standard deviation of 96 centimeters. What is the margin of error for

astraxan [27]

Answer:

D. 6

Step-by-step explanation:

Here we are given that a sample of 256 was taken from a population with a standard deviation of 96 centimeters i.e. $\sigma$ = 96 and n = 256.

And we have to calculate the margin of error for a 68% confidence interval.

Firstly from z score% table we observe that at 32% level of significance the z score critical value is given by 0.99744 .

And Margin of error formula is given by ;

$Z_\frac{\alpha}{2}$ * $\frac{\sigma}{\sqrt{n} }$ = 0.99744 * $\frac{96}{\sqrt{256} }$ = 5.98

Approximately, we get Margin of error = 6.

About how much more grape juice and orange juice is used in the punch

agasfer [191]

3 1/3 --> 3 8/24 --> 80/24

6 1/2 --> 6 12/24 --> 156/24

4 1/8 --> 4 3/24 --> 99/24

1 1/4 --> 1 6/24 --> 30/24

About how much more grape juice and orange juice is used in the punch

80/24+156/24 = 59/6 or 236/24

99/24+30/24= 43/8 or 129/24

236/24-129/24= 107/24 cups OR 4.458 cups OR 4 11/24 cups

About how much more grape juice than orange juice is used in the punch

3 1/3 --> 3 8/24 --> 80/24

6 1/2 --> 6 12/24 --> 156/24

approximately -3

hope this helps!

A landscaper needs 348 pounds of plant food. He has 114 pounds in his truck, and another 46 pound at his shop.

Black_prince [1.1K]

Answer:

$\frac{19}{12}\ pounds$

$1\frac{7}{12}\ pounds$

Step-by-step explanation:

The correct question is

A landscaper needs 3 4/8 pounds of plant food. He has 1 1/4 pounds in his truck, and another 4/6 pound at his shop. How many more pounds of plant food does the landscaper need?

Let

x ----> the additional pounds of plant food needed for the landscaper

we know that

The additional pounds of plant food needed for the landscaper plus the pounds in his truck plus the pounds in his shop must be equal to the total pounds of plant food needed

The linear equation that represent this problem is

$x+1\frac{1}{4}+\frac{4}{6}=3\frac{4}{8}$
