i'm confused, can you tell me the question?

Answer:

-2

Step-by-step explanation:

The 99[tex]\%[/tex] confidence interval for the difference between the mean yields for the two fertilizers is (32.11, 93.89).

A confidence interval is a range of values that provides an estimate of the unknown population parameter with a certain level of confidence.

Given that

Sample 1:

Sample mean, [tex]\bar{X_1}[/tex] = 457,

Sample size, [tex]n_1[/tex] = 18,

Standard deviation, [tex]s_1[/tex] = 38.

Sample 2:

Sample mean, [tex]\bar{X_2}[/tex] = 394,

Sample size, [tex]n_2[/tex] = 18,

Standard deviation, [tex]s_2[/tex] = 23.

Point estimate = [tex]\bar{X_1}[/tex] - [tex]\bar{X_2}[/tex]

                        = 457 - 394

                        = 63.

[tex]Standard Error=\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2} }\\[/tex]

                          [tex]=\sqrt{\frac{38^2}{18}+\frac{23^2}{18} }\\=11.14924[/tex].

Level of significance, α = 0.01 (given that 99[tex]\%[/tex] confidence interval).

Degrees of freedom = [tex]\dfrac{(\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2})^2 }{\frac{(\frac{s_1^2}{n_1})^2}{n_1-1} + \frac{(\frac{s_2^2}{n_2})^2}{n_2-1} }[/tex] = 28.

Critical values:

[tex]t_\frac{\alpha}{2} = \pm2.771[/tex]

The confidence interval is

[tex](\bar{X_1}-\bar{X_2})\pm t_\frac{\alpha}{2}\sqrt{\frac{s_1^2}{n_1}+\frac{s_2^2}{n_2} }[/tex]

[tex]= 63 \pm 2.771 \times 11.14924\\=63 \pm 30.89\\=(63-30.89,63+30.89)\\=(32.11,93.89)[/tex]

Hence, the confidence interval is (32.11, 93.89).

Answer:

a. [tex]\frac{1}{36}[/tex] chance you win.

b. The expected value of the game is -$2.08.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

You roll 2 die and if you toss 2 sixes

For each roll, 6 possible values, 1 of which is 6. So the probability of rolling two sixes is:

[tex]p = (\frac{1}{6})^2 = \frac{1}{36}[/tex]

a. What is the chance you win?

[tex]\frac{1}{36}[/tex] chance you win.

b. What is the expected value of the game?

1/36 probability of winning 100.

35/36 probability of losing 5. So

[tex]E = \frac{1}{36}*100 - \frac{35}{36}*5 = \frac{100 - 175}{36} = -\frac{75}{36} = -2.08[/tex]

The expected value of the game is -$2.08.

Step-by-step explanation:

I use a way that makes it easy for me

2:5 means [tex]\frac{2}{5}[/tex]

so when you write [tex]\frac{2}{5} =[/tex][tex]\frac{32}{x}[/tex]

that means you do the cross multiplication method which makes the equation go that way:

[tex]2x=32*5[/tex]

so

[tex]2x=160\\x= 80[/tex]

Hello!

[tex]\large\boxed{V = 425\pi cm^{3}}[/tex]

Use the following equation to solve for the volume of a cylinder:

V = πr²h, where:

r = radius

h = height

Plug in the given radius and height:

V = π(5)² · 17

Solve:

V = π(25 · 17)

V = 425π ≈ 1334.5 cm³

Answer:

12x + 15 = 12x - 15 can not be solved.

We can not find out what x equals.

Step-by-step explanation:

You can solve - 5x - 25 = 5x + 25

x = - 5

You can solve 7x + 21 = 21

x = 0

You can solve 12x + 15 = 3(4x + 5)

x = AllRealNumbers

That leaves 12x + 15 = 12x - 15

This equation can not be solved

a)

The test statistics is χ² = 8.31

b)

The critical value is 6.251.

c)

We reject the null hypothesis that the expected distribution is accurate.

Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.

It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.

We have,

a.

To test whether the expected distribution was accurate, we need to perform a chi-square goodness-of-fit test.

The null hypothesis is that the expected distribution is accurate, and the alternative hypothesis is that it is not accurate.

The expected frequencies are:

Color:

White  Black  Silver  Rose  Gold

105  122.5  70  52.5

i.e

Expected Freq:

0.3 x 350 = 105

0.35 x 350 = 122.5

0.2 x 350 = 70

0.15 x 350 = 52.5

Using the formula for the chi-square goodness-of-fit test statistic:

χ² = ∑ (Observed Frequency - Expected Frequency)² / Expected Frequency

χ² = [(99-105)²/105] + [(135-122.5)²/122.5] + [(89-70)²/70] + [(27-52.5)²/52.5]

χ² = 8.31

b.

The critical value for the chi-square test with 3 degrees of freedom (4 categories - 1) and a significance level of 0.10 is 6.251.

c.

Since the calculated test statistic (8.31) is greater than the critical value (6.251), we reject the null hypothesis that the expected distribution is accurate.

Therefore, the company cannot conclude that their expected distribution was accurate using a 10% level of significance.

Thus,

a)

The test statistics is χ² = 8.31

b)

The critical value is 6.251.

c)

We reject the null hypothesis that the expected distribution is accurate.
