Answer:

b = -2

Step-by-step explanation:

1) Cross multiply the proportion, in turn, you receive 2(b-4) = 6b.

2) Simply said equation, you should have 2b - 8 = 6b.

3) Subtract the 2b from each side, effectively canceling it out on the left (original position) and resulting in 6b to become 4b (6b - 2b = 4b).

4) After you have -8 = 4b, you can divide both sides by 4, canceling out on the right (original position).

5) You are finally left with -2 = b, reversing this results in b = -2.

-2 is your answer.

An SRS of ten brands of breakfast cereals is tested for the number of calories per serving. The following data result: 185, 190,

Pepsi [2]

Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval estimate for the mean number of calories for servings of breakfast cereals is (195.3, 215.7).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm t\frac{s}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.
t is the critical value.
n is the sample size.
s is the standard deviation for the sample.

From the sample and the significance level of 0.05, we have that the parameters are given by:

$\overline{x} = 205.5, s = 14.2, n = 10, t = 2.2622$

Hence:

$\overline{x} - t\frac{s}{\sqrt{n}} = 205.5 - 2.2622\frac{14.2}{\sqrt{10}} = 195.3$

$\overline{x} + t\frac{s}{\sqrt{n}} = 205.5 + 2.2622\frac{14.2}{\sqrt{10}} = 215.7$

The 95% confidence interval estimate for the mean number of calories for servings of breakfast cereals is (195.3, 215.7).
