In a survey of 118 randomly selected gun owners, it was found that 81 of them said they owned a gun primarily for protection.

Find the margin of error and 95% confidence interval for the percentage of all gun owners who would say that they own a gun primarily for protection. Report answers to at least 2 decimal places.

Margin of Error (as a percentage)

Answers

Answer 1

The margin of error is 0.086 and its C.I is (0.575 , 0.785).

What is margin of error?

Your results will vary from the actual population value by how many percentage points, as indicated by the margin of error. A 95% confidence interval with a 4% margin of error, for instance, indicates that your statistic will, 95% of the time, be within 4% of the true population figure.

n = 117 , x =87

Point estimate for the proportion:

P = x/n

= 81/118

= 0.68644

Confidence = 95%, α = 0.05

From z-table area 0.975 close to z=1.96

Margin of error, E = 1.96 √((0.68*0.55)/130)

= 1.96 * 0.05363

= 0.105

= 0.086

Confidence = P ± E

= 0.68 ± 0.105

=(0.68-0.105 , 0.68+0.105)

= (0.575 , 0.785)

Hence, the margin of error is 0.086 and its C.I is (0.575 , 0.785).

Rachel makes spirit bows for game day. She uses 48 feet of ribbon for 12 bows. If she uses the same amount of ribbon for each bow, how much ribbon would she need for 10 bows?

Answers

Answer:

40 ribbon

Step-by-step explanation:

We need to idenify the ratio which is 1 bow to 4 ribbons, so we times that by ten and we get 10:40 so its 40 ribbons. (Hope it helps)

The amount of ribbon she needs for 10 bows will be 40 feet.

What will be the quantity of ribbons for 10 rows?

It is given that

As she uses 48 feet of ribbon for 12 bows.

So for one bow, the ribbon will be

[tex]\dfrac{48}{12} =4[/tex]

So now if the size of the ribbon should be the same for the new 10 bows then

Size =[tex]10\times 4=40\ feet[/tex]

Thus the amount of ribbon she needs for 10 bows will be 40 feet

At a football game, 65% of people attending were supporting the home team, while 35% were supporting the visiting team. If 1300 people attending the game supported the home team, what was the total number of people attending the game? HELP ME I NEED AN A IN MATH!

Answers

Answer: 2000

Step-by-step explanation:

Percentage supporting home team = 65%

Percentage supporting visiting team = 35%

Number of people supporting home team = 1300

Let the total number of people attending the game be represented by x.

Therefore, 65% of x = 1300

65/100 × x = 1300

0.65 × x = 1300

0.65x = 1300

x = 1300 / 0.65

x = 2000

Therefore 2000 people attended the game.

Answer:

Step-by-step explanation:

The solution is, The mode and median are 7.

What is median?

In statistics and probability theory, the median is the value separating the higher half from the lower half of a data sample, a population, or a probability distribution. For a data set, it may be thought of as "the middle" value.

here, we have,

From the given dot plot, we can find the values.

Each X symbol corresponding to a number in the horizontal axis represents a value.

So, the data set can be written as,

3, 6,6,6,6,6,6,6, 7,7,7,7,7,7,7,7, 8,8,8,8,8,8, 9,9,9, 10,10

An outlier is value that lies outside the other values in the given data.

7 is a value which is close to the other values in the data set.

Hence, 7 is not an outlier.

Therefore, the statement "there is an outlier at 7 " is incorrect.

The total number of values can be found by counting the numbers in the data set after aarranging it in numerical order.

The total number of values in the data set is N=27.

The median is the middle value in a given data set.

Since N is odd, the position of the median is

median = 14

Since 7 is the 14 th value in the data set, the median is 7.

Mode is the value which repeats frequently in the given data set.

Since 7 is the most repeated value in the data set, 7 is the mode of the data set.

Hence, the statement "The mode and median are 7" is correct.

The range of a data set is the difference between the highest and the lowest values in the data set.

Hence, the range of the given data set is,

Hence, the statement " The range of the given data set is 10" is incorrect.

A dot plot is positive skewed if majority of the data is located to the right of the plot. The given dot plot is not positively skewed.

Hence, the statement " The data shows a positive skew" is incorrect.

Final Answer:

The mode and median are 7
