Suppose the restaurant’s description of the weights of its hamburgers is true. The dotplot below
shows the distribution of sample means from 100 simulated SRSs of size n = 5 from a normally
distributed population with µ = 8 ounces and σ = 0.54 ounces.
(b) Would it be unusual to get a sample mean of 7.6 oz or less in a sample of size n = 5 from this
population? Explain.
(c) Based on your answer to part (b), is there convincing evidence that the mean weight of
hamburgers at this restaurant is less than 8 oz? Explain.

Answers

Answer 1

Answer:

Step-by-step explanation:

It would be unusual because there are only one 7.6 samples out of a total of 100 samples.

PLEASE HELP ME QUICKLY!! The graph shows the number of eggs a farmer collected from each chicken pen one morning. How many more eggs were collected from pen 3 than from pen 2 & 5? (Each egg = 5 eggs)

Answers

Answer:

Pen 2 = 5 eggs

Pen 3 = 25 eggs

Pen 5 = 10 eggs

It is asking how many MORE eggs does pen 3 have from BOTH pens 2 and 5. Add 2 and 5. But remember one egg = 5 eggs so as stated in the beginning pen 2 has 1 egg which equals 5 eggs and pen 5 has 2 eggs which equals 10.

5 + 10 is?

15, exactly. So how many more eggs does pen 3 have? 15 + one more egg is 20 and pen 3 has 25 which is more than 20 so let’s add another egg which again equals 5.

Now we have 25 eggs, the exact amount pen 3 has. The answer is 2 more eggs/10 more eggs.

A rectangular field 50 metres wide and x metres long required 260 metres of fencing​

Answers

Answer:

x=80

Step-by-step explanation:

im going to assume this is perimeter.

50+50=100

260-100=160

160÷2=80

Answer:

5.2 metres in length I think

Step-by-step explanation:

you didnt exactly put a question, but this seems like a problem where you have to divided the volume by the width to find the length, so 260 divided by 50 is 5.2. I apologize if it is wrong, like I said, there wasn't a question so i was confused.

The seat of a bench is in the shape of a trapezoid with bases of 6 feet and 3 feet and a
height of 1.5 feet. What is the area of the seat?
The area of the seat is
ft.

Answers

Answer:

6.75 ft^2

Step-by-step explanation:

The area of the seat can be calculated as follows

a + b/2 × h

6+3/2 × 1.5

9/2 × 1.5

4.5× 1.5

= 6.75 ft^2

Answers

Answer:

R'(-5, -1) S'(-1, -1) T'(-1,-6)

Step-by-step explanation:

because the triangle is moving to the left, you subtract the number of units from the x coordinates of each vertex of the triangle. becasue the triangle is moving down, you subtract the number of units moved down from the y coordinates of each vertex.

Out of some students appeared in an examination,
80% passed in English, 75% passed in Science and
5% failed in both subjects. If 300 of them were
passed in both subjects, how many students were
appeared in the examination? Find it by using a
Venn-diagram
(Ans: 500​

Answers

Answer:

500 students appeared in the examination.

Step-by-step explanation:

Each event represents a set in the Venn diagram, and we use it to find the desired values.

I am going to say that:

Event A: Passed in English.

Event B: Passed in Science.

80% passed in English

This means that [tex]P(A) = 0.8[/tex].

75% passed in Science

This means that [tex]P(B) = 0.75[/tex]

5% failed in both subjects.

This means that 100% - 5% = 95% passed at least one of these subjects, so [tex]P(A \cup B) = 0.95[/tex].

Proportion that passed both subjects:

This is [tex]P(A \cap B)[/tex]

These percentages are related by the following equation:

[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]

So

[tex]P(A \cap B) = 0.8 + 0.75 - 0.95 = 0.6[/tex]

Number of students in class:

60% of the total number t passed both subjects. This is equals to 300. So

[tex]0.6t = 300[/tex]

[tex]t = \frac{300}{0.6}[/tex]

[tex]t = 500[/tex]

500 students appeared in the examination.
