Answer:

The confidence interval for the proportion of students supporting the fee increase

( 0.77024, 0.81776)

Step-by-step explanation:

<u>Explanation:</u>

Given data a survey of an urban university (population of 25,450) showed that 883 of 1,112 students sampled supported a fee increase to fund improvements to the student recreation center.

Given sample size 'n' = 1112

Sample proportion 'p' = $\frac{883}{1112} = 0.7940$

q = 1 - p = 1- 0.7940 = 0.206

<u>The 95% level of confidence intervals</u>

The confidence interval for the proportion of students supporting the fee increase

$(p-z_{\alpha } \sqrt{\frac{pq}{n} } ,p + z_{\alpha } \sqrt{\frac{pq}{n} } )$

The Z-score at 95% level of significance =1.96

$(0.7940-1.96\sqrt{\frac{0.7940 X 0.206}{1112} } ,0.7940 + 1.96 \sqrt{\frac{0.7940 X 0.206}{1112} } )$

(0.7940-0.02376 , 0.7940+0.02376)

( 0.77024, 0.81776)

<u>Conclusion:</u>-

The confidence interval for the proportion of students supporting the fee increase

( 0.77024, 0.81776)

3.25 liters.

<h3>Further explanation</h3>

<u>Given:</u>

Mrs.Henderson makes punch by mixing 10.9 liters of apple juice, 0.6 liters of orange juice, and 8 liters of ginger ale.
She poured equally into 6 bowls.

<u>Question:</u>

How much punch is in each bowl?

Express your answer in liters.

<u>The Process:</u>

The two steps for obtaining the amount of punch in each bowl are as follows:

<u>Step-1: </u>the total amount of punch after mixing is the sum of apple juice, orange juice, and ginger ale in liters.

$\boxed{ \ 10.9 \ liters + 0.6 \ liters + 8 \ liters = 19.5 \ liters \ }$

<u>Step-2: </u>the total amount of punch divided by the number of the bowl is the amount of punch in each bowl.

$\boxed{ \ 19.5 \ liters \div 6 \ bowls = \boxed{ \ 3.25 \ liters/bowl \ } \ }$

Let's also consider the following quick steps.

<u>Quick steps:</u>

$\boxed{ \ \frac{(10.9 + 0.6 + 8) \ liters}{6 \ bowls} = \frac{19.5 \ liters}{6 \ bowls} = \boxed{ \ 3.25 \ liters/bowl \ } \ }$

Therefore, the amount of punch in each bowl is 3.25 liters.

Your friend uses the equation c=50p to find the total cost c for the number of people p internal local amusement park create a t

AnnZ [28]

We are given equation c=50p.

c is the total cost and p is the number of people.

Let us take number of people by groups of 10, 20, 30,40 people.

Note: We can take any positive integer for number of people in a group.

Now, we need to plug p=10, 20, 30,40 one by one in given function c=50p to find the costs c.

Plugging p=10, we get

c= 50*10 = 500.

Plugging p=20, we get

c= 50*20 = 1000.

Plugging p=30, we get

c= 50*30 = 1500.

Plugging p=40, we get

c= 50*40 = 2000.

So, we can create a table as.

Number of people (p) Total cost (c)

10 500

20 1000

30 1500

40 2000
