Answers

Answer:

The width of the confidence interval is going to be wider

Step-by-step explanation:

When we Increase the level of confidence without changing the sample size the width of the confidence interval is going to be affected in the following way;

The margin of error (M.E) is going to be larger or be increased. This increase is due to the fact that the critical value is going to increase. Then the increased margin of error would cause the width of the confidence interval to become wider.

A company manufactures batteries in batches of 26 and there is a 3% rate of defects. Find the standard deviation for the number of defects per batch.

Answers

Answer:

The standard deviation for the number of defects per batch is 0.87.

Step-by-step explanation:

Let X denote the number of defective batteries per batch.

A company manufactures batteries in batches of n = 26.

It is provided that the rate of defects is, p = 0.03.

Each battery is defective independently of the others.

The random variable X follows a binomial distribution.

The standard deviation of a binomial distribution is:

[tex]\sigma=\sqrt{np(1-p)}[/tex]

Compute the standard deviation for the number of defects per batch as follows:

[tex]\sigma=\sqrt{np(1-p)}[/tex]

  [tex]=\sqrt{26\times 0.03\times (1-0.03)}\\\\=0.86982757\\\\\approx 0.87[/tex]

Thus, the standard deviation for the number of defects per batch is 0.87.

Answers

1. you have to subtract 9 from both sides. 21-9= 12
2. you have to add 2x to both sides. 4x+2x= 6x
3. 6x divided by both sides =

The required real-world problem is below that can be solved using the equation.

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

A construction company is building a new housing development and wants to know how many houses they need to build to reach a certain profit margin. They know that each house costs $9 to build and they want to sell each house for $21.

If they build x number of houses, the equation to calculate their profit is:

21x - (4x + 9) = profit.

To reach a certain profit margin, the company can set that equation equal to a specific value and solve for x.
