A survey was conducted to compare the mean cost of a meal at fast food restaurants in two different cities.

City n x s

A 26 $4.05 $0.55

B 32 $5.15 $0.85

Assume that the population variances of both groups are different. Test if there is sufficient evidence that the mean costs of a meal at fast food restaurants in two different cities are different. Conduct the hypothesis testing (optional) in paper.

Answer:

We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.

Step-by-step explanation:

Given :

City n x s

A 26 $4.05 $0.55

B 32 $5.15 $0.85

H0 : μ1 - μ2 = 0

H0 : μ1 - μ2 ≠ 0

n1 = 26 ; x1 = 4.05 ; s1 = 0.55

n2 = 32 ; x2 = 5.15 ; s2 = 0.85

Tstatistic :

(x1 - x2) / √(s1²/n1 + s2²/n2)

(4.05 - 5.15) / √(0.55²/26 + 0.85²/32)

-1.1 / 0.1849668

= - 5.947

Using the smaller n;

df = n - 1 ; 26 - 1 = 25

Pvalue = (-5.947, 24)

Pvalue = 0.000001

Since Pvalue < α ; We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.

For each of the following, indicate whether or not a paired analysis would be appropriate.

a. A school cafeteria offers a vegetarian and a nonvegetarian option for lunch every day. For a period of two weeks, you record how many calories are in the vegetarian option and how many calories are in the nonvegetarian option. Your goal is to see if vegetarian options tend to differ with regard to average number calories from nonvegetarian options.

b. A farmer investigates whether talking to cows by name leads to producing more milk. He randomly selects 30 of his cows and randomly assigns 15 to talk to by name and the other 15 not to.

Answer: a. a paired analysis is appropriate

b. a paired analysis is not appropriate

Step-by-step explanation:

The paired analysis sometimes is refered to as a statistical procedure which is used to know if the mean difference that exist between two observations is zero or not. It should be noted that in a paired analysis, each subject is measured twice, and this beings about the pairs of observations.

a. Here, the paired analysis is appropriate due to the fact that similar measurement which are the calories are taken for several days for both the vegetarian and the non vegetarian such are two pairs of sample.

b) In this case, the paired analysis is not appropriate. Here, the pairs of samples don't undergo identical treatment.

**Answer:**

The simplest way to prove that triangles are congruent is to prove that all three sides of the triangle are congruent. When all the sides of two triangles are congruent, the angles of those triangles must also be congruent. This method is called side-side-side, or SSS for short.

Can you help on #5 I have to estimate & #5 simple yes or no please thank you

If you need an estimate for #5, then you can round each value to the nearest whole number to have...

21.6 turn into 2120.9 turn into 2119.4 turn into 1918.5 turn into 19Add up those values: 21+21+19+19 = 80

-------------------

Another estimate you could do is to round everything to 20, since we're close to this value. Having four copies of 20 added leads to 20+20+20+20 = 80

So they rode a **total estimated amount of 80 miles**

--------------------

The actual total is: 21.6+20.9+19.4+18.5 = 80.4 miles, which isn't too far off from 80.

a trader bought some eggs at 64 per dozen and sold 2/3 of them at 240/= per tray and the other 1/3 at 225/= per tray.In so doing she made a profit of 450/=.given 1 tray holds 30 eggs and 1 dozen 12 eggs determine the number of eggs she bought.

Note that the number of eggs the above-described **trader **bought is** 180 eggs.** This is solved using simple **arithmetic**.

Let no. of the eggs be x, then

Money the trader paid for eggs = 64/12x = 16/3x

The money the **trader **got from

Seling two third eggs =2/3x*240/30

=16/3x

Money get from one third= x/3*225/30

=5/2

Profit= [16/3x+5/2x] - 16/3x

5/2x = 450

x =450*2/5

=180

Therefore, the **number of eggs** that the trader bought is **180.**

The length of a rectangular lot is 6 feet less than 3 times its

width. Its area is 222 square feet.

Its width is

feet and its length is

feet.

**Answer:**

Its width is 9.66 feet and length is 22.98 feet.

**Step-by-step explanation:**

Let l is length and b is width of a rectangular lot.

Length, l = (3b-6) feet

The area of the lot is 222 sq feet.

The area of a rectangle is given by :

[tex]A=lb\\\\222=(3b-6)b\\\\222=3b^2-6b[/tex]

It is a quadratic equation. The solution of the above equation is given by :

b = 9.66 feet and -7.66 feet

Neglecting negative answer, the width of the lot is 9.66 feet.

Length, l = (3(9.66)-6) = 22.98 feet

**Hence, its width is 9.66 feet and length is 22.98 feet.**

O The margin of error is multiplied by 0.5.

O The margin of error is multiplied by 2.

**Answer:**

The margin of error is multiplied by 4.

**Step-by-step explanation:**

**Margin of error is:**

[tex]M = \frac{zs}{\sqrt{n}}[/tex]

In which z is related to the confidence level, s is elated to the standard deviation and n is the sample size.

From this, we have that the standard deviation is inversely proportional to the square root of the sample size.

**If you cut the sample size in half:**

The margin of error is inversely proportional to the square root of the sample size, so if you cut the sample size by [tex]\frac{1}{2}[/tex], the margin of error will be multiplied by [tex]2^2 = 4[/tex]

So

The margin of error is multiplied by 4.

**Answer:**

D) y=-5/2x; y=-20

**Step-by-step explanation:**

If y varies directly with x, then y=kx where k is our proportionality constant

Therefore, since y=-5 when x=2, we have -5=k(2) where k=-5/2

This means that when x=8, y=(-5/2)(8)=-20, making choice D correct
