There is no prior information about the proportion of Americans who support the gun control in 2018. If we want to estimate 99%
Romashka-Z-Leto [24]

Answer: 13

Step-by-step explanation:

If the prior population proportion is unavailable then the formula to find the sample size is given by :-

n=0.25(\dfrac{z^*}{E})^2

, where z* = Critical z-value

E = margin of error

Let p be the proportion of Americans who support the gun control in 2018.

As per given , we have

Confidence level = 99%

The critical z-value for 99% confidence interval is 2.576  ( BY z-table)

Margin of error : E= 0.36

Since there no  prior information about the proportion of Americans who support the gun control in 2018.

So , the required sample size  to estimate 99% confidence interval would be:

n=0.25(\dfrac{2.576}{0.36})^2=0.25(7.16)^2

n=0.25(51.2656)=12.8164\approx13

Hence,  13 Americans should be surveyed.

1) Find the minimum and maximum values for the function with the given domain interval.
Julli [10]

Answer:

"minimum value = 0; maximum value = 8"

Step-by-step explanation:

This is the absolute value function, which returns a positive value for any numbers (positive or negative).

For example,

| -9 | = 9

| 9 | = 9

| 0 | = 0

Now, the domain is from -8 to 7 and we want to find max and min value that we can get from this function.

If we look closely, putting 7 into x won't give us max value as putting -8 would do, because:

|7| = 7

|-8| = 8

So, putting -8 would give us max value of 8 for the function.

Now, we can't get any min values that are negative, because the function doesn't return any negative values. So the lowest value would definitely be 0!

|0| = 0

and

ex:  |-2| = 2 (bigger),  |-5| = 5 (even bigger).

So,

Min Value = 0

Max Value = 8
